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.
据报道,具有三氟甲硫醇盐阴离子的1,2-和1,3-氨基磺酸盐的区域和立体选择性开环。此直接引入整个SCF的3基序是朝向β-和γ-SCF一个简单的合成路线3个胺和α-氨基酸衍生物。通过将Cys(S -CF 3)掺入二肽和三肽中进一步说明了该反应的效用。
