摘要：

A synthetic method for isoquinoline synthesis via a [4+2] annulation of N-H imines with alkynes using the high-valent (pentamethylcyclopentadienyl)cobalt(III) [Cp*Co(III)] catalyst is described. Cerium(IV) sulfate was found to be an efficient oxidant in lieu of the commonly used copper or silver salts. Broad substrate scope, high functional group tolerance, and generally good yields were observed.
