presented of the use in peptide synthesis of esters for which aminolysis is assisted by a neighbouring group. 2-Pyridylthiolesters of phthaloyl-, benzyloxycarbonyl-, and t-butoxycarbonyl-amino-acids are described, and it is shown that they condense very rapidly even with hindered amino-esters to give high yields of protected dipeptides. Phthaloyl-L-phenylalanine pyrimidin-2-yl thiolester is also described
