A new and versatile synthetic route to Securinega alkaloids is reported. The first synthesis of allosecurinine has been accomplished in seven steps and 40% yield, starting from (+)-menisdaurilide, using a vinylogous Mannich reaction as the key transformation. Similarly, viroallosecurinine has been synthesized from (-)-menisdaurilide.
据报道,一种新的,通用的合成Securinega生物碱的途径。使用乙烯基类曼尼希反应作为关键转化,从(+)-menisdaurilide开始,以7个步骤和40%的产率完成了Allosecurinine的首次合成。类似地,已经从(-)-半月桂脲内酯合成了四氢阿糖嘌呤。
