A novel three-step entry toward phthalazine derivatives has been elaborated. A strategy based on a sequential acyl-alkylation/diazo transfer reaction/Diaza-Wittig reaction led to the desired analogues in moderate to good yields from an aryne precursor. Various aryl groups were introduced on the annulated pyridazine, moreover the presence of an ester group allows further modifications.
已经详细说明了向酞嗪衍生物的新颖的三步法。基于顺序的酰基-烷基化/重氮转移反应/ Diaza-Wittig反应的策略从芳烃前体以中等至良好的产率产生了所需的类似物。将各种芳基引入到环式哒嗪上,此外,酯基的存在允许进一步修饰。
