new series of ring-expanded nucleic acid analogues to be useful as building blocks in the design of mixed base functional genetic systems. While exploring alternative pathways to oxepine nucleoside synthesis, we discovered an unprecedented α-stereoselective O-glycosylation of 1,2-glucals under mild Simmons–Smith conditions.

葡萄糖的扩环合成了一系列含有各种核碱基(A、U、T、5-FU、C)的七元(恶庚英)核苷。我们期望这一系列新的扩环
核酸类似物能够作为混合碱基功能遗传系统设计的构建模块。在探索氧杂平核苷合成的替代途径时,我们发现在温和的 Simmons-Smith 条件下,1,2-
葡萄糖醛酸会发生前所未有的 α-立体选择性O-糖基化。
