A number of alkynols have been prepared by Sonogoshira coupling of propargyl alcohol to disubstituted aromatic halides. Chelation controlled addition of organometallic nucleophiles to these alkynols was then affected followed by the addition of sulfur dioxide. This methodology was used to prepare a number of oxathiolene oxides which have been screened as NQO1 (quinone oxidoreductase) inducers.
通过
丙炔醇与二取代芳香卤化物的 Sonogoshira 偶联,制备出了许多炔醇。在这些炔醇中加入有机
金属亲核物后,再加入
二氧化硫进行螯合控制。这种方法被用来制备一些氧化
硫烯氧化物,这些氧化物已被筛选为 NQO1(醌氧化还原酶)诱导剂。
