1,2-Disubstituted Alkenes as Migratory Insertion Participants in Zn(II)-Promoted Metalloamination/Cyclization of N,N-Dimethylhydrazinoalkenes

摘要

Diethylzinc-mediated metalloamination/cyclization of unsaturated N,N-dimethylhydrazines has been extended to the use of 1,2-disubstituted alkenes as N-Zn migratory insertion acceptors. Representative 2-arylethenes and vinylcyclopropanes readily serve as reaction participants in metalloamination/cyclization allylation cascades.
