摘要
The first organocatalytic asymmetric addition of thiols to N-acyl ketimines, which are generated in situ from 3-hydroxy isoindolinones, is described. The reaction proceeds smoothly with a broad range of ketimines and thiols using a chiral Bronsted acid catalyst to afford N(acyl),S-acetals comprising a tetrasubstituted stereocenter in high yields and enantioselectivities (up to 98.5 : 1.5 e.r.). The usefulness of the developed protocol is demonstrated in the synthesis of a known HIV-1 reverse transcriptase inhibitor.
