摘要
trans-Cumylcyclohexanol (TCC) is used as a chiral auxiliary for the stereoselective addition of tributyltinlithium to N-acylpyrrolidinium/piperidinium ion with 70-80% diastereoselectivity at 0degreesC. After removal of the minor diastereomer by radial chromatography, enantiopure N-methyl-2-(tributylstannyl)pyrrolidine and piperidine were produced by reductive removal of the auxiliary.
