Crystal structure of 4-(1R2S5R)-2-isopropyl-5-methyl­cyclo­hex­yl 2-methyl (2S4S5R)-1-(2S3R5R)-5-meth­oxy­carbonyl-2-(2-methyl­phen­yl)pyrrolidine-3-carbon­yl-5-(2-methyl­phen­yl)pyrrolidine-24-di­carboxyl­ate

摘要

The title compound, C38H50N2O7, represents a chiral β-proline dipeptide. Corresponding stereogenic centres of constituting pyrrolidine units have opposite absolute configurations. The central amide fragment is planar within 0.1 Å and adopts a Z configuration along the N—CO bond. In the crystal, the hydrogen atoms of the methyl­ene groups form several short inter­molecular C—H⋯O contacts with the carbonyl oxygen atoms of an adjacent mol­ecule. The only active amino hydrogen atom is not involved in hydrogen bonding.
