Novel syntheses of tetrahydrobenzodiazepines and dihydropyrazines via isocyanide-based multicomponent reactions of diamines

In this work, two novel isocyanide-based mul multicomponent reactions of 1,2-diamine compounds with diketene have been developed as efficient strategies for the synthesis of 2,3,4,5-tetrahydro-lH-benzo[b][l,4]diazepine2-carboxamidcs with regiochemical control and 1,6-dihydropyrazinc-2,3-dicarbonitrilcs in good to excellent yields at ambient temperature.

An Easy Route to Synthesize 1,5-Arylodiazepin-2-ones

A series of 1,5-arylodiazepin-2-ones is prepared by the condensation of the approptiate o-β-arylenediamines with β-ketoesters in xylene under microwave irradiation.The reaction time is shortened to 10 mn, and the products are obtained in high yields.No by products are observed.Specific effects of microwaves are evidenced as no reaction occurs by classical heating in same conditions. - Key Words: Condensation; Microwave; 1,5-Arylodiazepin-2-ones.

Synthese et reactivite de nouvelles molecules de type bis--1,n alcanes

A number of bis-1,n- alkanes have been prepared by reaction between 4-phenyl (4-cyclopropyl and 4-methyl)-2,3-dihydro 1,5-benzodiazepine 2-one and dihalogenoalkanes X-(CH2)n-X under phase transfer catalysis conditions.The action of hydrazine at different concentration on this structure have been studied.These products have been characterized by NMR 1H, IR, MS and the microanalysis.

N-Bridged Heterocycles. Part 5. α,ω-Bis-(2-oxobenzimidazolinyl)-alkanes and -ethers as Selective Ligands for Group-1 and -2 Metals

A series of the title compounds (10), (12), and (13) and several analogues were synthesised from the readily available 1-isopropenylbenzimidazolin-2-one.Various substituents were attached to the unsubstituted nitrogen atoms of the benzimidazolinone moieties and the series of products obtained were tested for their complexing ability with group-1 and -2 metal-salts.The isolation of crystalline complexes, the solubilisation of the salts in chloroform by ligand, the i.r. carbonyl absorption shift, and the ion-transport ability of the ligand were examined as an index of complexation.Selective complexation, particularly for calcium, was noted in several cases.
