A stereoselective synthesis of the C1-C14 fragment of thiomarinols is disclosed. The key steps include the stereoselective preparation of an allylic sulfide via a chloro sulfide by 1,2-asymmetric induction, ring-closing metathesis reaction, Kirmse-Doyle reaction for the preparation of a γ,δ-unsaturated ester, Nozaki-Hiyama-Kishi coupling and Julia-Kocienski olefination reaction. Substrate controlled
公开了硫代水杨醇的C1-C14片段的立体选择性合成。关键步骤包括通过1,2-不对称诱导经由氯硫化物立体选择性制备烯丙基硫化物,闭环易位反应,用于制备γ,δ-不饱和酯的Kirmse-Doyle反应,Nozaki-Hiyama-Kishi偶联和Julia-Kocienski烯烃化反应。底物控制的不对称诱导已有利地用于产生立体异构中心。Noyori转移氢化和不对称氢化反应已用于创建甲醇立体中心。
