Vilsmeier-Haack Reagents. Novel Electrophiles for the One-Step Formylation of O-Silylated Ethers to O-Formates

Abstract

Various O-silylated substrates were effectively converted in one-step to their corresponding O-formates using electrophilic racemic and homochiral Vilsmeier-Haack reagents. Reactivity trends of these transformations were examined that, specifically, emphasized their synthetic potential.

Vilsmeier-Haack complexes - deprotection of O-silyl ethers - one-step deprotection - preparation of O-formates - formyl glycosides
