The regio- and stereoselective ring opening of 1,2- and 1,3-sulfamidates with trifluoromethanethiolate anion is reported. This direct introduction of the whole SCF3 motif is a straightforward synthetic route toward β- and γ-SCF3 amines and α-amino acid derivatives. The utility of this reaction was further illustrated by incorporation of Cys(S-CF3) into di- and tripeptides.
