摘要：

Peracetylated sugars can be efficiently converted into the corresponding 1,2-ethylidenes, -orthoesters, and -glycals via the in situ generation of glycosyl iodides promoted by I-2/Et3SiH. The approach is straightforward and avoids isolation of the sensitive iodinated intermediates. (C) 2003 Elsevier Ltd. All rights reserved.
