Stereoselective nucleophilic addition of PhSCF<inf>2</inf>SiMe<inf>3</inf> to chiral cyclic nitrones: Asymmetric synthesis of gem-difluoromethylenated polyhydroxypyrrolizidines and -indolizidines

© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Fluoride-catalyzed nucleophilic addition of a difluoro(phenylsulfanyl)methyl group ("PhSCF2") generated from PhSCF2SiMe3 to nitrones was accomplished in satisfactory yields. High diastereoselectivities were observed with chiral polyo...
