摘要

Efficient Boc protection of amines was carried out using (Boc) 2 O in the presence of a catalytic amount of ZrCl 4 (10 mol %) in acetonitrile at room temperature. The reaction times are very short and the yields are generally high. ... Efficient Boc protection of amines using (Boc) 2 O in the presence of a catalytic amount of ZrCl 4 (10 mol %) in acetonitrile at room temperature is reported with short reaction times and high yields. ... Among the various protecting groups used for ...
