Amidation of amino acids using dichloro(methyl)(3,3,3-trifluoropropyl)silane (MTFPSCl2) and imidazole is described. MTFPSCl2 activates the carboxy group and protects the α-amino group of amino acids. The amidation proceeded with 19 amino acids and 19 amines, including α-branched amines and anilines; the corresponding amino acid amides were synthesized in good-to-high yields (up to 96%) with low-to-no
描述了使用二氯(甲基)(3,3,3-三氟丙基)硅烷(MTFPSCl 2)和咪唑对氨基酸进行酰胺化。MTFPSCl 2活化羧基并保护氨基酸的α-氨基。酰胺化进行了19个氨基酸和19个胺,包括α-支化胺和苯胺;相应的氨基酸酰胺以高至高产率(高达 96%)合成,外消旋化低至无。
