One-pot synthesis and structure∑property relationship of aminomaleimides: Fluorescence efficiencies in monomers and aggregates easily tuned by switch of aryl and alkyl

Organic fluorophores have attracted great interest owing to their wide applications. They usually contain an electron-conjugated system with an aromatic moiety and show high emission in dilute solutions but weaker or even no emission upon aggregation. Her

Synthesis of fused pyrrolo[3,4-d]tetrahydropyrimidine derivatives by proline-catalyzed multicomponent reaction

Novel proline-catalyzed multicomponent reactions (MCRs) for the synthesis of fused pyrrolo[3,4-d]tetrahydropyrimidines 7 and 9 with different substituted patterns have been developed, which provide rapid access to a library of compounds 7 and 9 in medium to excellent yields, by using N-methyl-α- aryl(alkyl)aminomaleimides, amines, and aldehydes as reactants. The catalyst and the ratio of reactants were found to have significant impact on these reactions, and a reasonable mechanism was also proposed.

Lewis acid-promoted cascade reaction of primary amine, 2-butynedioate, and propargylic alcohol: A convenient approach to 1,2-dihydropyridines and 1H-pyrrolo[3,4-b]pyridine-5,7(2H,6H)-diones

1,2-Dihydropyridine-5,6-dicarboxylates were efficiently constructed through a cascade reaction of primary amine, 2-butynedioate and propargylic alcohol in the presence of Lewis acid under mild conditions. As exceptional, 1H-pyrrolo[3,4-b]pyridine-5,7(2H,6

Synthesis of 1-alkyl-3-arylamino-pyrrole-2,5-diones

Reaction of 1-alkyl-3-alkylaminopyrrole-2,5-diones with primary arylamine hydrochlorides in methanol or DMSO gives 1-alkyl-3-arylaminopyrrole-2,5-diones which could also be obtained from the reaction of arylaminofumarates with primary aliphatic amines.
