Abstract

A cascade C–H functionalization/C(sp3)–C(sp3) formation/cyclization reaction of N-methoxybenzamides with diazomal­onates under rhodium(III) catalysis is developed for the efficient synthesis of isoquinolinedione derivatives. A plausible mechanism involving double migratory insertions of carbenes for the formation of C(sp2)–C(sp3) and C(sp3)–C(sp3) bonds by rhodium(III) catalysis is also proposed.
