摘要：

Benzannulation of C-ethynyl glucoside 1 with electrophilic chromium carbene 2 affords Cr(CO)(3)-coordinated hydroxynaphthyl C-glycoside 3. The metal carbonyl fragment can be shifted by haptotropic migration or removed upon oxidation to give aryl C-glycosides 4 and 5. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
