Copper-catalyzed alkenylation of novel N-iodoarylated allylic ketopiperazinonates with unactivated alkenes

Abstract

N-Aryl-substituted piperazines constitute the core of several pharmacologically pertinent targets such as the antidepressant trintellix. We herein demonstrate that novel N-iodoaryl-substituted allylic ketopiperazinonates are amenable to efficient CuBr-catalyzed alkenylation with simple alkenes to afford N-stilbeno or styrenyl piperazine derivatives.
