Facile preparation of the N-acetyl-glucosaminylated asparagine derivative with TFA-sensitive protecting groups useful

Abstract:
In this study, a novel N-acetyl-glucosaminylated asparagine derivative was developed. This derivative carried TFA-sensitive protecting groups and was derived from commercially available compounds only in three steps. It was applicable to the ordinary 9-fluorenylmethoxycarbonyl (Fmoc)-based solid-phase peptide synthesis (SPPS) method, and the protecting groups on the carbohydrate moiety could be removed by a single step of TFA cocktail treatment generally used for the final deprotection step in Fmoc-SPPS.

Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
