An aza-Wittig-type reaction of bis(iminophosphorane) 2 with two moles of alkyl or aryl iso(thio)cyanates leads to indazolotriazolobenzotriazepines 7.The bis(iminiphosphorane) 4 reacts with aromatic iso(thio)cyanates to give
Iminophosphorane-mediated synthesis of functionalized indoles and 1,3-benzodiazepines
Molina,Arques,Alias,Vinader
, p. 4401 - 4404 (2007/10/02)
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.
