efficient methods were explored for the synthesis of various conjugated exo-glycals: (i) by nucleophilic addition of sugar lactones with a subsequent dehydration, and (ii) by selenylation of C-glycosides with a subsequent selenoxide elimination. These reactions occurred in a stereoselective manner to give exclusively or predominantly the (Z)-isomers of exo-glycals.
探索了两种用于合成各种缀合的外糖的有效方法:(i)通过亲核加糖内酯并随后进行脱水,以及(ii)C-糖苷的硒化并随后去除亚硒氧化物。这些反应以立体选择性方式发生,以仅或主要给出外糖的(Z)-异构体。
