The synthesis of a natural product family: from debromoisolaurinterol to the aplysins
Total syntheses of (+/-)-aplysin 1, (+/-)-debromoaplysin 2, (+/-)-isoaplysin 3, (+/-)-aplysinol 4, (+/-)-debromoaplysinol 5, (+/-)-aplysinal 6, (+/-)-isolaurinterol 7 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.

Abstract
Total syntheses of (+/-)-aplysin 1, (+/-)-debromoaplysin 2, (+/-)-isoaplysin 3, (+/-)-aplysinol 4, (+/-)-debromoaplysinol 5, (+/-)-aplysinal 6, (+/-)-isolaurinterol 7 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.
