Abstract

A new intramolecular acyl transfer from aglycon to sugar moiety in C-glucopyranoside has been observed. This unusual acyl transfer reaction has been extended to the regioselective and direct acylations of 2′-hydroxyl group of free C-glucopyranoside and one step syntheses of four natural C-glycosylchromones from aloesin glucopyranoside have also been achieved by this method.© 1997 Elsevier Science Ltd.
