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