A new domino strategy for the synthesis of highly functionalized quaternary imidazole derivatives via [3 + 2] heterocyclization, involving aryl migration and ring-opening of oxirane, has been developed. This domino reaction enables the successful assembly of three new sigma bonds including two C–N bonds in a simple operation. Features of this strategy include the mild conditions, convenient operation
已开发出一种新的多米诺骨牌战略,该战略通过[3 + 2]杂环化合成高度官能化的季咪唑衍生物,涉及芳基迁移和环氧乙烷的开环。这种多米诺骨牌反应可通过简单的操作成功组装三个新的sigma键,其中包括两个C–N键。该策略的特点包括条件温和,操作方便以及反应时间短(15-20分钟)。
