In this article, a one-pot protocol was established for the synthesis of ketopiperazine-substituted quinone derivatives. This method based on the building blocks of piperazine ketone enamine ester 1, which reacted with quinones 2 through α-C selective alkylation of the enamine ester and via dehydrogenation oxidation reaction in acetonitrile at room temperature and acetic acid as catalyst. As a result, a series of novel ketopiperzine-substituted quinone derivatives 3a~3l have been synthesized efficiently with 70%~88% yield. This method possesses some advantages such as simple synthetic route, readily available starting materials, high yields and simple work-up procedures.

Key words: enamine ester, ketopiperzine, quinone derivatives, acetic acid, selective alkylation
