Abstract
A radical addition/cyclization reaction of o-isocyanodiaryl amines has been developed for the efficient synthesis of potentially bioactive dibenzo[b,e][1,4]diazepine-11-carboxylates and dibenzo[b,e][1,4]diazepine-11-carboxamides. This Fe(acac)2/TBHP-promoted radical cascade process involves an unexplored isocyanide addition and the following cyclization to form 11-functionalized dibenzodiazepines. Moreover, the alkoxycarbonylation and carboxamidation of o-isocyanodiaryl amines show broad substrate scope and good functional group compatibility under mild conditions.

Abstract
A general method to construct the scaffolds of dibenzooxazepine and dibenzodiazepine, through Pd-catalyzed isocyanide insertion and intramolecular C(sp2)-H activation, has been developed. This is the first example of seven-membered heterocycle formation by C-H imidoylative annulation.
