A New Highly Regioselective Reaction of Unprotected Sugars for Chemical Synthesis of Methyl-6-D-acyl-D-glycopyranosides by Mean of Chlorophosphoric Acid Diethyl Ester[(C2H5O)2P(:O)Cl] as Condensing Reagent
摘要:
A new methodology which allows the regioselective acylation of no protected methyl-D-glycopyranosides at the primary hydroxy group is described. Thus, a new synthetic procedure is presented to synthesize 6-acyl-methyl-glycopyranosides from unprotected glycopyranosides by means of (EtO)2P:OCl as condensing reagent.
