摘要

Abstract A direct and highly convenient organocatalytic method for the preparation of 1, 5- dialdo-pyranosides and 1, 4-dialdo-furanosides is presented. The method relies on the chemoselective properties of TEMPO in combination with trichloroisocyanuric acid under very mild, basic conditions. Unprotected glycosides are prepared in a single step in high yields and are efficiently purified with the use of solid-phase imine capture.(© Wiley-VCH ...
