We report a concise synthesis of tanikolide 1, which was obtained from ethyl 2-oxocyclopentanecarboxylate in four steps: alkylation, Baeyer–Villiger reaction, saponification, and reduction/lactonization, in 70% overall yield. Our strategy should be suitable for the preparation of 1 in multigram or larger quantities. The net result of the last two steps (i.e. saponification and reduction/lactonization)
我们报告了由2个羰基环戊烷甲酸乙酯分四个步骤制得的tanikolide 1的简明合成方法:烷基化,Baeyer-Villiger反应,皂化和还原/内酯化,总收率为70%。我们的策略应适合于以1克或更大的量制备1。最后两个步骤(即皂化和还原/内酯化)的最终结果是有效地还原了3的乙氧基羰基,同时保持了内酯羰基的完整性。
