Cross-dehydrogenative coupling reactions have been utilized to alkylate 4(3H)-quinazolinones with ethers and amides, using catalytic n-Bu4NI and t-BuOOH as oxidants. The reactions with amides represent the first examples under such conditions. Studies via inter- and intramolecular competitive experiments with protio and deuterio reactants, as well as radical inhibition experiments, provided mechanistic
使用催化n -Bu 4 NI 和t -BuOOH作为氧化剂,交叉脱氢偶联反应已用于将 4(3 H )-喹唑啉酮与醚和酰胺烷基化。与酰胺的反应代表了这种条件下的第一个例子。通过质子和氘代反应物的分子间和分子内竞争性实验以及自由基抑制实验进行的研究提供了机理见解。此外,通过与 4(3 H )-喹唑啉酮的成对竞争获得了对醚类相对反应性的理解。
