Abstract

Abstract: A simple, inexpensive and efficient method for the selective cleavage of N-Boc protecting group under acidic conditions on high load Wang resin is described. This method employs the use of concd sulfuric acid in 1, 4-dioxan and provides an efficient process for the complete Boc deprotection with minimal loss of substrate through cleavage from resin. Key words: solid phase synthesis, selective N-Boc cleavage, high load Wang resin
