A concise, flexible, and linear approach has been devised for the total synthesis of the resorcinylic acid lactones (S)-zearalenone (2) and (R)-de-O-methyllasiodiplodin (4) by using a Stille cross-coupling strategy. The other key steps of the synthesis include a ring-closing metathesis (RCM), a chemoselective reduction of an α,β-unsaturated ketone, and a transesterification reaction.
通过使用 Stille 交叉偶联策略,设计了一种简洁、灵活和线性的方法来全合成间苯二酸内酯 (S)-玉米赤霉烯酮 (2) 和 (R)-de-O-methyllasiodiplodin (4)。合成的其他关键步骤包括闭环复分解 (RCM)、α,β-不饱和酮的化学选择性还原和酯交换反应。
