of natural products are small α-methylene bis-γ-lactones that exhibit a wide variety of biological activities. Herein we report concise syntheses of five members of this family of natural products along with the synthesis of one non-natural analogue. The syntheses proceed in five or six steps from simple, commercially available compounds and feature a key oxidative cyclization/lactonization reaction
天然产物阿文酸内酯是小的α-亚甲基双-γ-内酯,具有多种生物活性。在此,我们报告了该天然产物家族的五种成员的简明合成以及一种非天然类似物的合成。从简单的可商购化合物开始,合成过程分五步或六步进行,并且具有可能通过自由基机理发生的关键氧化环化/内酯化反应。
