addition to an in-situ-generated lactaldehyde. The resulting homoallylic alcohol was further transformed into a set of ring-closing metathesis (RCM) precursors. These compounds were converted into noviose in few steps using RCM and RCM-allylic-oxidation sequences.
稀有碳水化合物 L-(+)-noviose 是由对映异构纯 L-乳酸合成的。C-4 处的构型是通过对原位生成的乳醛进行非对映选择性亲核加成来建立的。所得高烯丙醇进一步转化为一组闭环复分解 (RCM) 前体。使用 RCM 和 RCM-烯丙基氧化序列,通过几个步骤将这些化合物转化为 noviose。
