摘要

The direct O-formylation of two selectively protected sugar derivatives using the Vilsmeier-Haack (V-H) complex (POCl3DMF)-D-. was studied. Primary O-TBDMS and O-TBDPS ethers of sucrose, the most common disaccharide, underwent regio and chemoselective O-formylation with this formylating agent. This conversion was also studied with a monosaccharide analogue. (C) 2004 Elsevier Ltd. All rights reserved.
