T3P (propylphosphonic anhydride) mediated conversion of carboxylic acids into acid azides and one-pot synthesis of ureidopeptides

Basavaprabhu,Narendra,Lamani, Ravi S.,Sureshbabu, Vommina V.

, p. 3002 - 3005 (2010)

A general, mild, efficient, and environmentally benign protocol, which makes use of T3P as an acid activating agent for the direct synthesis of acid azides from carboxylic acids is described.
