The lipase-mediatedkineticresolution of compound 1 was investigated to prepare chiral synthons showing oxygenatedstereotriads in a definiteconfigurational arrangement. These key intermediates were embedded in biologically relevant structures, such as hydroxylated pyrrolidine 3 and C-phenyl glycosides by classical organic reactions.

A novel method for synthesis of polysubstituted pyrrolidines, which possess a C-2 stereocenter, was developed. The strategy involves Grignard addition to the succinimide, derived from L-tartaric acid, followed by stereocontrolled triethylsilane promoted reduction of the resulting cyclic amidols.
