Ma. Barsy et al., A facile synthesis of new pyrazolo- and triazolo[5,1-c] [1,2,4]triazepine derivatives via intermolecular Wittig ring-closure reaction, HETEROCYC C, 6(6), 2000, pp. 545-551
In view of the potential biological activity of fused azepines(1-4) and in
connection with our interest in the synthesis of new heterocycles.(5-8) we
report here on the synthesis of the title triazepines, a type of compounds
rarely mentioned in literature as possible effective drugs.(9-11)
