Amine-catalyzed formation of cyclic allylic nitro compounds via nitro-aldol reaction is disclosed. A greener solvent and a cheaper, more robust catalyst than in previous reports are used in the nitro-aldol reaction. After screening a range of catalysts the reaction is developed as a selective method of synthesis of α-dehydroherbac and the scope is demonstrated with a small collection of additional substrates.
本研究公开了胺催化下通过硝基-醛醇反应生成环状烯丙基硝基化合物的方法。在硝基-醛醇反应中使用了比以往报告中更环保的溶剂和更便宜、更坚固的催化剂。在对一系列催化剂进行筛选后,该反应被开发为一种选择性合成 α-脱氢海巴戟的方法,并通过少量其他底物证明了该方法的适用范围。
