Convenient synthesis of novel 2-substituted imidazopyrazinone derivatives

Starting from commercially available piperazine-2-carboxylic acid, a series of novel 2-aryl and 2-benzyl substituted imidazopyrazinone were prepared. The intermediates 5a-g were obtained through facile Buchwald-Hartwig coupling reaction, and the effects of catalyst, base, and solvent on the coupling reaction were investigated. The optimal reaction conditions for the coupling reaction were PdCl2(dppf)=NaO-t-Bu=toluene. Taylor & Francis Group, LLC.
