A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.
一、发现了2-位氧化α-甲基D-葡萄糖苷的芳胺亲核加成引起羰基转位的新方法,利用核磁共振氢谱及碳谱对邻苯二胺与2-位氧化α-甲基D-葡萄糖苷加成生成的稳定中间体半缩酮化合物在氘代丙酮中的变化进行跟踪,结合对转化产物的氢氢相关谱和HMQC结构确证,提出了该反应中2-位羰基通过烯醇化互变而转至3-位的机理并得到了验证。
