Abstract

Abstract The deracemization by enantioselective protonation of silyl enol ethers was tested using 2, 2-dimethyl 5-phenyl 1, 3-dioxolan 4-one 1. The results obtained, especially with pantolactone as a chiral proton donor, are better than when the deracemization is carried out with the lithium enolate of 1.
