Abstract A synthesis of a series of N??alkoxycarbonyl mercaptobenzothiazoles (MBTs) and their application as reagents for chemoselective protection of amino group are presented herein. It was shown that all new reagents, Z??MBT, Fmoc??MBT, Phoc??MBT, and Tec??MBT, are highly effective in the selective N??alkoxycarbonylation of (S)??isoserine. The transformation is a simple, fast, and low??cost protocol, which is applicable in scale??up ...
