摘要：

Disarmed glycosyl trichloroacetimidates can be activated by Yb(OTf)(3) in the synthesis of 1.2-trans glycosides involving primary and secondary acceptors. Concurrent formation of orthoester side products can be avoided by the use of alkoxycarbonyl groups for the protection of the donor 2-hydroxyl. (C) 2001 Elsevier Science Ltd. All rights reserved.
