Abstract: A facile, elegant, and operationally simple van Leusen protocol for the synthesis of bicyclic dihydrodibenzo[b,f]imidazo[1,2-d][1,4]thiazepines and dihydrodibenzo[b,f]imidazo[1,2-d][1,4]oxazepines is developed. The reaction proceeds without any catalyst and in high yields to provide bicyclic imidazo-dibenzothia-/oxazepines at room temperature… read more here.
