Abstract

N-benzyl-cinchonidinium bromide, C26H29N2O+·Br-, with the systematic name (R)-[(2S,4S,5R)-1-benzyl-5-ethenyl-1-azoniabi-cyclo-[2.2.2]octan-2-yl](quinolin-4-yl)-methanol bromide, is a quaternary ammonium salt of the cinchona alkaloid cinchonidine. This salt is widely used as a chiral phase-transfer catalyst and chiral resolution agent. Both classical and non-classical hydrogen-bonding inter-actions, as well as anion effects have been shown to play key mechanistic roles in the catalysis of cinchona alkaloids. In an effort to understand the effects of water on these inter-molecular inter-actions, the structures of anhydrous N-benzyl-cinchonidinium bromide, (I), and the sesquihydrate, C26H29N2O+·Br-·1.5H2O, (II), were determined. © Janzen et al. 2022.

Chemical context

Cinchona-derived enanti­oselective phase-transfer catalysts have been used in a variety of applications including [2,3]-Wittig rearrangements (Denmark & Cullen, 2015 ▸), synthesis of unnatural α-amino acids (O’Donnell et al., 1989 ▸), and even industrial-scale synthesis of pharmaceuticals (Moccia et al., 2015 ▸). As this class of phase-transfer catalysts are easy to prepare from the parent natural product alkaloids, and demonstrate aspects of green and sustainable chemistry, they are attractive organocatalysts for further development. Mechanistic studies of N-benzyl­cinchonidinium bromide and substrates in solution provide evidence for the importance of quaternary ammonium benzylic C—H hydrogen-bond donor inter­actions as well as the classical OH donor (Bencivenni et al., 2021 ▸). Anion effects also demonstrate differences in the binding mode of substrates with mechanistic implications and potential enanti­oselectivity. While structures are reported for analogs of this cation, that of the commercially available bromide salt is unpublished. We report here the structures of N-benzyl­cinchonidinium bromide (I) and the sesquihydrate (II).

Structural commentary

The anhydrous compound (I) (Fig. 1 ▸) crystallizes in the monoclinic space group P21. The asymmetric unit of (I) consists of one mol­ecular cation and one bromide anion. The sesquihydrate (II) (Fig. 2 ▸) crystallizes in the tetra­gonal space group P41212. The asymmetric unit of (II) consists of one mol­ecular cation, one bromide anion, and one water on a general position and one half water, as O3 lies on a twofold axis at z = 0.5. For (I) and (II), the absolute configuration of chiral atoms N1, C2, C3, C7, and C8 are determined as S, R, S, S, and R, respectively, by anomalous dispersion and are consistent with previous structures of cinchonidine.

Most analogous bond lengths in (I) and (II) show only minor differences, with two exceptions (Tables 1 ▸ and 2 ▸). The largest differences in bond lengths occur for C6—C7 [1.510 (4) Å (I), 1.553 (8) Å (II)] and N2—C11 [1.282 (6) Å (I), 1.319 (9) Å (II)]. The quinuclidine intra­molecular N1⋯C3 distances show small expansion of this bicyclic ring system from (I) [2.534 (5) Å] to (II) [2.591 (8) Å]. Overlap of the N-benzyl­cinchonidinium cation atom coordinates of (I) and (II) (Fig. 3 ▸) shows significant conformational differences. While the quinuclidine, benzyl, and vinyl functionalities adopt very similar conformations for (I) and (II), larger changes are observed in the alcohol and quinoline groups. Torsion angles that highlight the largest conformational changes include C7—C8—C13—C12 [107.9 (3)° (I); 101.3 (7)° (II)], C8—C7—N1—C20 [−39.0 (3)° (I); −53.6 (7)° (II)], and O1—C8—C13—C12 [−11.7 (4)° (I); −19.2 (8)° (II)]. These torsion-angle differences result in large changes in the relative angles between least-squares planes of the phenyl and quinoline groups in (I) [14.8 (2)°] and (II) [41.8 (3)°]. Intra­molecular C—H⋯O contacts C5—H5A⋯O1 are found in both (I) and (II), but (I) shows an additional benzylic C20—H20B⋯O1 contact (Tables 3 ▸ and 4 ▸, Figs. 4 ▸ and 5 ▸).

Supra­molecular features

The extended structure of (I) displays a simple isolated charge-assisted hydrogen bond with the alcohol donor O1 and Br1 anion acceptor (Table 3 ▸, Fig. 4 ▸). The quinoline N2 acceptor does not participate in any hydrogen-bonding inter­actions. Each bromide also has four short C—H⋯Br contacts with the same cation (phenyl, benzyl, quinoline, and vin­yl) as well as an additional quinuclidine methine C—H. The sesquihydrate (II) shows very different hydrogen-bonding inter­actions (Table 4 ▸, Fig. 5 ▸). The alcohol group O1 acts as a donor with a water acceptor, O2. Water O2 hydrogen bonds as donor with Br1 and quinoline N2, while water O3 acts a donor to two bromide acceptors. This pattern of hydrogen bonds forms a chain with terminal O1 donors and water and bromide links, with the water O2 relating the two halves of the chain. Quinoline N2 acceptors of O2 hydrogen-bond donors link the chains forming an extended network. Each bromide also has four short C—H⋯Br contacts with the same cation (benzyl, vinyl, and two quinuclidine) as well as two additional quinuclidine contacts with a neighboring mol­ecular cation (Figs. 5 ▸ and 6 ▸).

Database survey

A search of the Cambridge Structural Database (ConQuest version 2022.1.0; Groom et al., 2016 ▸) yields several related analogs of both N-benzyl­cinchonidinium salts as well as the pseudo-enanti­omer N-benzyl­cinchoninium. The 2-fluoro­benzyl bromide sesquihydrate analog XUNQIG (Jew et al., 2002 ▸) is isostructural with (II) though additional C—H⋯F intra- and inter­molecular inter­actions are present. Introduction of the aromatic 2-fluoro substituent yielded enhanced enanti­oselectivity in catalytic phase-transfer alkyl­ation reactions, with possible origins related to more conformational or dipole changes to enhance substrate binding. Other closely related N-benzyl­cinchonidinium chloride salts have been employed in co-crystal resolution of a chiral spiro­cyclic diol (GAJBOJ01; Zhang et al., 2006 ▸), atropisomeric chiral diols (HADSIS; Walsh et al., 2021 ▸ and JAPGIR; Sweetman et al., 2005 ▸) and a related mixed chiral amine/alcohol (GOSWIU; Ding et al., 1999 ▸). Even in the presence of multiple additional hydrogen-bond donors in these co-crystals, short benzylic C—H⋯Cl contacts are retained in GAJBOJ01 and JAPGIR, though not in HADSIS or GOSWIU. The N-benzyl­cinchonidinium cation has also been employed in resolution of chiral halogenated phosphates (GARJUF, GAWSUT; Frantz et al., 2005 ▸). Short benzylic C—H⋯O contacts are found in these chiral phosphate salts. Closely related cinchoninium anhydrous bromide structures with phenyl substituents [2-bromo­benzyl, QEDZAC (Skórska-Stania et al. 2012 ▸) and 3,5-bis­tri­fluoro­methyl, UHINUV (Kawai et al., 2009 ▸)] show similar O—H⋯Br hydrogen bonding to (I). However, the C—H⋯Br inter­actions differ. In QEDZAC, each bromide has quinuclidine, quinoline, and benzyl C—H⋯Br contacts with the same cation. In UHINUV, quinoline, benzyl, and phenyl C—H⋯Br contacts with the same cation are found. The N-benzyl­cinchoninium chloride salt has also been employed in a co-crystal resolution of BINOL (WOMQUK01; Walsh et al., 2021 ▸).

Synthesis and crystallization

N-benzyl­cinchonidinium bromide was purchased from Sigma-Aldrich (St. Louis, Missouri, USA). Crystals of the anhydrous form (I) were obtained by vapor diffusion of diethyl ether into an aceto­nitrile solution of N-benzyl­cinchonidinium bromide. Crystals of the sesquihydrate (II) were obtained by slow evaporation of an ethanol solution of N-benzyl­cinchonidinium bromide.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 5 ▸. The O—H hydrogen positions were assigned from residual electron-density peaks and positions were refined. All remaining hydrogen atoms were placed in calculated positions and refined in the riding-model approximation with distances of C—H = 0.93, 0.93, 0.93, 0.97, and 0.98 Å for the aromatic C—H, terminal vinyl CH2, vinyl C9—H9, methyl­ene C—H, and methine C—H, respectively, and with U iso(H) = k·U eq(C), k = 1.2 for all C—H and 1.5 for the hydroxyl H1.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
