摘要

Participating acyl groups located at C-2 in glucosyl and related donors generally promote formation of 1, 2-trans-glycosides. Reactions of some glucuronic acid donors with TMSN3/SnCl4 or ROH/SnCl4 gave only the 1, 2-cis-glycoside. The stereoselectivity is consistent with participation of the C-6 group. The methodology was used for the synthesis of a Kdn2en mimetic with the α-configuration.
