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
摘要:
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.
