A highly-enantioselective acylation of silyl ketene acetals with acyl fluorides has been developed to generate useful α, α-disubstituted butyrolactone products. This reaction is promoted by a new thiourea catalyst and 4-pyrrolidinopyridine and represents the first example of enanti-oselective thiourea anion-binding catalysis with fluoride.
