New scaffolds for drug discovery, 6-azaspiro[4.3]alkanes, have been synthesized in two steps from four-membered-ring ketones: cyclobutanone, thienone, N-Boc-azetidinone (Boc = tert-butoxycarbonyl), etc. The key transformation was the reaction between electron-deficient exocyclic alkenes and an in-situ generated N-benzylazomethine ylide.
用于药物发现的新支架,6-氮杂螺[4.3]烷烃,由四元环酮分两步合成:环丁酮、噻吩酮、N-Boc-氮杂环丁酮(Boc = 叔丁氧基羰基)等。 关键转化是缺电子环外烯烃与原位生成的 N-苄基偶氮甲碱叶立德之间的反应。
