文摘

A number of azoloquinazolines has been efficiently synthesized in the cyclocondensation reaction of azoloazines with α,β-unsaturated carbonyl compounds activated with ultrasound. Two main advantages of the suggested procedure are shorter reaction time and higher yields compared to reflux and stirring at room temperatures. In addition, the yields of dehydrogenization products were decreased.
