The first total synthesis of sperabillin A and an improved total synthesis of sperabillin C have been achieved in 11 steps from N-Boc-O-methyl-L-tyrosine. The stereoselective pathway to the core (3R,5R)-3,6-diamino-5-hydroxyhexanoic acid involves an Arndt-Eistert homologation, an asymmetric Henry reaction and a ruthenium tetroxide-catalyzed oxidative degradation of a benzene ring as key steps.
从 N-Boc-O-甲基-L-酪氨酸通过 11 个步骤实现了第一次全合成 sperabillin A 和改进的 sperabilin C 全合成。核心 (3R,5R)-3,6-二氨基-5-羟基己酸的立体选择性途径涉及 Arndt-Eistert 同源性、不对称亨利反应和四氧化钌催化的苯环氧化降解作为关键步骤。
