A one‐pot method for the transformation of secondary alcohols to α‐hydroxy ketones using pyridinium dichromate (PDC) at room temperature is described. The method was tested with a variety of hydantoin derivatives. As a direct application, total synthesis of four natural oxoaplysinopsins D, E, F and G was accomplished for the first time through a common dihydroxy intermediate.
描述了一种在室温下使用重铬酸吡啶鎓(PDC)将仲醇转化为α-羟基酮的一锅法。用多种乙内酰脲衍生物测试了该方法。作为直接的应用,四种天然的氧代皂甙酶D,E,F和G的全合成是通过共同的二羟基中间体首次完成的。
