Asymmetric twin-ring differentiation by lipase-catalyzed enantiotoposelective reaction of the ring-crossed meso glycol: Asymmetric synthesis of a highly functionalized piperidine from the conjoined twin piperidine system

Article abstract of DOI:10.1016/S0040-4039(00)79101-5

Both enantiomers of the homochiral 3-oxygenated 2,6-cis-disubstituted piperidine 1 were synyhesized by starting with lipase-catalyzed transesterification or hydrolysis of the meso glycol or its diacetate in the conjoined twin piperidine system.
