Syntheses of Nucleoside Derivatives Containing Fmocor Trityl-protected Amino Acids

摘要

Facile direct esterification reactions between 2′,3′-O-isopropylidene-nucleosides and Fmoc- or trityl-protected amino acids %via% N,N-dicyclohexyl-carbodiimide(DCC) mediated condensation are described. These reactions offer a mild and convenient method to synthesize aminoacylated nucleoside derivatives.
