Abstract

The protecting group plays important role in synthesis of multifunctional targets. A simple rapid efficient and green method for chemo-selective N-Boc protection of amines using Lithium hydroxide as a green catalyst. In the present work amine protection in presence of ditert-butyl carbonate under solvent free condition is carried out. An efficient green protocol for chemoselctive N-Boc protection of aryl, aliphatic, aromatic, acyclic and hetero cyclic amines (1 m mol %)( 10, 20, 30) were carried out with ditert-butyl carbonate (Boc)2 O using Lithium hydroxide monohydrate (10 mol %) at room temperature under solvent free condition to give white solid monitored on TLC. No side reactions are observed .The present protocol were simple, rapid, efficient, shorter reaction times, high yielding, highly selective, economical and eco-friendly
