nitroarenes under basic conditions. The reaction proceeded according to the vicarious nucleophilic substitution of hydrogen scheme; i.e. the initially formed σ-adducts underwent base-induced elimination, resulting in cleavage of the cyclopropane ring. The ortho-substituted products can be directly transformed into substituted N-hydroxyindoles.
在碱性条件下,使1-
氰基-2,2-二乙氧基羰基
环丙烷与几种硝基
芳烃反应。反应根据氢方案的亲核取代进行。也就是说,最初形成的σ加合物经历了碱诱导的消除,导致
环丙烷环断裂。的邻位-取代的产品可直接转化为取代的Ñ -hydroxyindoles。
