Diazabicyclic alkenes

More recently, a palladium-catalyzed tandem protocol for the synthesis of cyclopentene fused heterocycles from diazabicyclic alkenes and ortho-functionalized atyl iodides was elaborated. A number of cyclopentene fused dihydrobenzofurans and indolines were prepared by this procedure (Scheme 2.50). The reaction can he tuned toward the formation of either...
