Selected AbstractsMild Synthesis of ,-Amino-,,,-difluoro Ketones from Acylsilanes and Trifluoromethyltrimethylsilane in a One-Pot Imino Aldol Reaction,EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 20 2005Sylvain Jonet Abstract ,-Amino-,,,-difluoro ketones have been very conveniently prepared in a one-pot procedure from acylsilanes, trifluoromethyltrimethylsilane and imines. The key intermediate in this reaction is a difluoroenoxysilane. The Lewis acid promoted imino aldol reaction was performed with BF3·OEt2 or under very mild conditions using a catalytic amount of Yb(OTf)3. The reaction with chiral benzylimines occurred in good yield with 52,78,% de. Palladium-catalyzed hydrogenolysis furnished an unprotected ,-amino-,,,-difluoro ketone or a ,-amino-,,,-difluoro alcohol. (© Wiley-VCH Verlag GmbH & Co.
