diols is described. The key step is a high-yielding, diastereoselective LaCl3·2LiCl-mediated addition of a Grignard or organolithium reagent to ketone 2a. The reaction is believed to proceed via a 1,3-chelated intermediate. One of the adducts has been transformed into a functionalized cyclopentenone resembling the core structure of pactamycin.
描述了合成分化的邻级叔二醇的策略。关键步骤是高产率,非对映选择性的LaCl 3 ·2LiCl介导的格氏试剂或有机锂试剂加到酮2a上。据信该反应通过1,3-螯合的中间体进行。其中一种加合物已被转化为类似于pactamycin核心结构的功能化环戊烯酮。
