Methyl (2S,6S:2R,6R)-6-(2-cyanoethyl)-4,6-dimethyl-2-morpholineacetate.

The morpholine ring of the title compound, C12H20N2O3, adopts a chair conformation with an equatorial (methoxycarbonyl)methyl group. The cyanoethyl and (methoxycarbonyl)methyl groups are trans with respect to each other. The global minimum conformation, as computed by PCMODEL [Gajewski & Gilbert (1992). Molecular Modeling Package. Version 4.0], of the title compound agrees with that observed in the crystal. In the crystal, the torsion angles (N identical to)C-CH2-CH2-C(O), (N identical to C)CH2-CH2-C-O, O-CH-CH2-C(OOCH3) and (O)CH-CH2-C(O)-O(CH3) have values -170.0 (1), -45.9 (2), -71.6 (2) and 142.8 (1) degrees, respectively.
