Abstract
Abstract An efficient protocol for the synthesis of Nα-protected carbodiimides has been achieved. Nα-protected ureas were treated with P2S5 to obtain the essential precursors, thioureas. Protected thioureas undergo dehydrosulfurization in the presence of di-tert-butyl dicarbonate (Boc)2O and base catalyst 4-dimethyl amino pyridine (DMAP), to yield corresponding carbodiimides. The synthesized compounds were mainly gums, a few were solids, after the simple workup, and were characterized by IR, 1H NMR, 13C NMR and HRMS.
