Iminophosphorane-mediated synthesis of functionalized indoles and 1,3-benzodiazepines

Aza Wittig-type reaction of bis(iminophosphorane) 2 with aromatic isocyanates leads to either indoles 5 or pyrimido[4,5-b]indoles 6, whereas with aliphatic isocyanates and acyl chlorides afforded pyrrolo[2,3-b]indoles 7 and 1,3-benzodiazepines 10 respectively.
