Reaction of alpha-tetralone, 1H-tetrazol-5-amine, and aromatic aldehydes upon microwave irradiation - a convenient method for the synthesis of 5,6,7,12-tetrahydrobenzo[h]tetrazolo[5,1-b]quinazolines

摘要

A multicomponent reaction between alpha-tetralone, 1H-tetrazol-5-amine, and aromatic aldehyde, occurring upon microwave irradiation in acidic medium at 130A degrees C, led to the formation of previously unknown 7-aryl-5,6,7,12-tetrahydrobenzo[h]tetrazolo[5,1-b]quinazolines in 5-52% yields.
