Concise One-Pot Preparation of Unique Bis-Pyrrolidinone Tetrazoles

Concise copper-catalyzed one-pot tandem synthesis of benzimidazo[1,2-b]isoquinolin-11-one derivatives.

A simple and efficient copper-catalyzed one-pot tandem method has been developed for synthesis of benzimidazo[1,2-b]isoquinolin-11-one derivatives via reactions of substituted 2-halo-N-(2-halophenyl)benzamides with alkyl 2-cyanoacetates or malononitrile under mild conditions.

One-pot preparation of substituted pyrroles from α-diazocarbonyl compounds

In this work an efficient one-pot synthesis of substituted pyrroles 7a-n is described, which involves the in situ formation of dihydrofurans ethyl 5-butoxy-2-methyl-4,5-dihydrofuran-3-carboxylate (4), 1-(5-butoxy-2-methyl-4,5-dihydrofuran-3-yl)ethanone (5) and 5-butoxy-4,5-dihydrofuran-3-carbaldehyde (6) followed by reaction with primary amines.

Bis(benzylamine) monomers: One-pot preparation and application in dendrimer scaffolds for removing pyrene from aqueous environments

Bisimine and bisamine AB2 monomers have been synthesized from 3,5-diaminobenzoic acid and benzaldehyde derivatives without the need for protective groups or purification. This monomer preparation is universal for various electron-donating and electron-withdrawing benzaldehyde substrates. To demonstrate the versatility of these previously unreported AB2 monomers in the formation of high molecula...
