Iron-catalyzed hydroalkylation of quinoxalin-2(1H)-ones with alkenes and phenylsilane.
A practical protocol has been established for the synthesis of dihydroquinoxalin-2(1H)-ones through iron-mediated hydroalkylation of quinoxalin-2(1H)-ones with alkenes and phenylsilane. The reaction proceeds smoothly at room temperature, utilizing alkenes as the alkylating agents and phenylsilane as the hydride source,...
