Herein, we report the total synthesis of traumatic lactone and rhizobialide by utilizing allenoic acid to construct the lactone ring. The key starting materials, allenoic acids, could be prepared by the ATA (allenation of terminal alkynes) of a terminal alkyne with an aldehyde that contained a protected hydroxyl group followed by hydrolysis. Importantly, the asymmetric synthesis could be realized just
在本文中,我们报道了通过利用烯丙酸构建内酯环,可合成创伤性内酯和根瘤菌的总合成物。关键的原料是烯丙酸,可以通过末端炔与含有受保护的羟基的醛的ATA(末端炔的烯丙基化)制备,然后水解。重要的是,不对称合成可以仅通过用(R)-或(S)-二苯基普萘酚代替外消旋的二苯基普萘酚来提供旋光性脲基甲酸酯来实现。
