The total synthesis of restrictinol, the hydrolysis product of the antifungal natural product restricticin, starting from commercially available methyl (S)-(+)-3-hydroxy-2-methylpropionate is described. Key stages in the strategy involved (i) the use of Brown's allylboration chemistry to construct an acyclic intermediate bearing three of the four stereogenic centers of the natural product, (ii) formation
描述了从可商购获得的(S)-(+)-3-羟基-2-甲基丙酸甲酯开始的限制素(抗真菌天然产物限制素的水解产物)的全合成。该策略的关键阶段涉及(i)使用Brown的烯丙基硼化化学技术构建一个无环中间体,该中间体带有天然产物的四个立体异构中心中的三个,(ii)形成C-糖苷乙烯基碘,以及(iii)引入三烯侧链通过铃木偶联反应。
