STEREOSELECTIVE SYNTHESIS OF 3,4-DISUBSTITUTED CYCLOPENTANONES AND RELATED COMPOUNDS

Methods and materials for preparing optically active 3,4-disubstituted cyclopentanones are disclosed. The method includes hydrolyzing one or more compounds represented by Formula (13), or removing an ester moiety from a compound represented by Formula (18).

Asymmetric synthesis of 1,3- and 1,3,4-substituted pyrrolidines

Diastereoselective alkylation of N-acylnorbornene sultams 2 afforded a variety of enantiomerically pure products 3a-3e. Reduction with LiAlH4 (LAH) followed by ditosylation furnished chiral 1,4-ditosylates 5a-5e which underwent a cyclization reaction with primary amines to afford chiral 1,3- and 1,3,4-substituted pyrrolidines.
