The examples of regiospecificity reactions of dienones derivatives of cyclohexane are made. On basis of 6-benzylidene -2-(5-nitrohetarilmetilidene) cyclohexanones were synthesized previously unknown dibromadducts, hexahydroindazoles and triazolochinazolines. The structure of derived compounds was ascertained by spectral methods. The probable reaction schemes are shown.
