Similar acylations of indoloquinazolinone have also been performed with four different acyl chlorides. In all examples, facile rearrangement of imine double bond from quinazolinone to indole moiety to form the corresponding alpha,beta-unsaturated carbonyl system is observed.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><custom3><style face="normal" font="default" size="100%">Indian</style></custom3><custom4><style face="normal" font="default" size="100%">0.471</style></custom4></record></records></xml>
