Abstract

The title compound, C(33)H(49)NO(3), is the propargyl-amide of 18β-glycyrrhetinic acid, a penta-cyclic triterpenoid of inter-est as a therapeutic agent. The five six-membered rings of the glycyrrhetinic acid moiety show normal geometries, with four rings in chair conformations and the unsaturated ring C in a half-chair conformation. In the crystal, the terminal N-propargylcarboxamide group has remarkable structural effects on weak hydrogen-bond-like inter-actions. Particularly noteworthy are an inter-molecular O-H⋯π inter-action accepted side-on by the terminal alkyne group [O⋯C = 3.097 (2) and 3.356 (2) Å] and a short inter-molecular C-H⋯O inter-action [C⋯O = 3.115 (2) Å] donated by the alkyne C-H group. An N-H⋯O [N⋯O = 3.251 (2) Å] and a C(alkyl)-H⋯O [C⋯O = 3.254 (2) Å] interaction complement the crystal structure.

Geometry. All e.s.d.'s are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
