The use of a CoBr2/1,10-phenanthroline catalytic system together with Zn as the reductant was developed to prepare diversely substituted indanamines by a Co(I)-catalyzed [3 + 2] annulation of o-haloaryl imines with electron-deficient alkenes in good yields. The use of Mn as the reductant allowed the elaboration of a three-component version of this reaction. These conditions were also found to be suitable

We report a new synthetic method for the synthesis of a family of dibenzodiazepines (DBDAs), employing Pd-catalyzed C–N coupling of o-bromoaldimine, with o-bromoaniline as the key step.
