and (±)-debromoisolaurinterol 8 are described. Key features are a diastereoselective, sulfur mediated radical cyclisation of diene 12 to give 35; a new radical to polar crossover sequence mediated by Bu3Sn that transforms diene 12 into (±)-debromoisolaurinterol 8; and a series of biomimetic cyclisation and oxidation reactions.
(±)-aplysin 1,(±)-debromoaplysin 2,(±)-isoaplysin 3,(±)-aplysinol 4,(±)-debromoaplysinol 5,(±)-aplysinal 6,(±)-isolaurinterol的总合成描述了图7和(±)-异溴异十二烷基尿嘧啶醇8。主要特点是一个非对映选择性,硫介导的二烯基团环化12得到35 ; 由Bu 3 Sn介导的新的自由基至极性交换序列将二烯12转变为(±)-debromoisolaurinterol 8 ; 以及一系列仿生环化和氧化反应。
