Succinimido enaminonas foram sintetizadas através da reação de enaminonas e a N-(p-toluil)-maleimida em rendimento moderado a bom. A ação antibacteriana destes compostos contra E. coli e S. aureus foi avaliada, mas a atividade antibacteriana não foi significativa. A regioquímica das succinimido enaminonas foi racionalizada empregando-se a teoria dos orbitais moleculares de fronteira. A estrutura cristalina de um dos compostos foi determinada e foram observadas várias pontes de hidrogênio inter-e intramolecular do tipo NH...O e CH...O.The reaction of N-(p-tolyl)-maleimide with enaminones afforded succinimide-containing enaminones in moderate to good yields, and these compounds were evaluated against E. coli and S. aureus, but no significant antibacterial activity was observed. The regiochemistry of the compounds was examined mechanistically within frontier molecular orbital considerations. In the solid state three-dimensional structure there is the formation of cooperative inter-and intramolecular NH...O and CH...O hydrogen bonding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
