Abstract
AbstractThe reaction of cyclic enaminones with arylidenemalononitriles was carried out in the presence of 13X molecular sieves in dimethyl sulfoxide. Under these mild reaction conditions, various bioactive N-aryl-4-arylhexahydroquinoline derivatives were obtained in high yields without the necessity of using transition-metal catalyst, organobase, or reflux conditions.
