A practical approach for the synthesis of novel triazolo-fused benzazepine derivatives using a multi-component reaction and an intramolecular C-H arylation

An efficient and straightforward method has been developed for the preparation of triazolo-fused benzazepines by a facile, one-pot Ugi multi-component reaction/click reaction. In this strategy, the Ugi-reaction products were coupled by a click reaction, thus integrating the triazole fragment into the benzazepine structure using an intramolecular C-H arylation. The corresponding products were obtained in good yields without unfavourable by-products.
