Abstract
We have studied the electronic effect of substituents, steric factors, the medium, and the nature of the oxidizing agent on oxidative cyclocondensation of 2-thioxo-4-quinazolone and its substituted derivatives. We have found that electron-donor substituents promote the reaction while electronacceptor substituents inhibit the reaction.
