Enantioselective acylation of silyl ketene acetals through fluoride anion-binding catalysis. Journal of the American Chemical Society 133(35): 13872 -13875.0002-7863http://nrs.harvard.edu/urn-3:HUL.InstRepos:8737992A highly-enantioselective acylation of silyl ketene acetals with acyl fluorides has been developed to generate useful \(\alpha\), \(\alpha\)-disubstituted butyrolactone products. This reaction is promoted by a new thiourea catalyst and 4-pyrrolidinopyridine and represents the first example of enantioselective thiourea anion-binding catalysis with fluoride.en-USJournal Article2012-05-1410.1021/ja205602j
