Abstract

Reactions of pyridynes with cyclic urea and 1-methyl-2-oxazolidone were demonstrated. 3,4-Pyridyne and 2,3-pyridyne were reacted with N,N-dimethylimidazolidone, N,N-dimethylpropylene urea, and 1-methyl-2-oxazolidone to give the corresponding pyridodiazepines, pyridodiazocines, and pyridooxazepines, respectively.
