A highly improved one-pot procedure for the synthesis of diazepinones, which incorporate a bioactive quinoline nucleus, under catalyst-, and solvent-free environment has been developed. The method allowed us to achieve the products in high yields without requiring a chromatographic separation. All new quinolyldibenzo [b, e][1, 4] diazepinones 6a–h thus obtained were further treated to achieve N10–allylated products 7a–h by a simple ...
