摘要

Boron enolates derived from α-heterosubstituted thioacetates and bearing menthone- derived chiral ligands react with aldehydes to give anti aldols with excellent diastero-and enantiocontrol. Boron enolates derived from tert-butyl α-halothioacetate and bearing menthone-derived chiral ligands react with imines with excellent diastero-and enantiocontrol to give syn α-halo-β-aminothioesters, which can be converted to the corresponding ...
