A new series of tetrahydroindeno[1,2-b]pyrrole-3-carboxylate derivatives(4) were synthesized by reaction of 5-amino-2-mercapto benzimidazole with 1,3-dicarbonyls and activated carbonyl compounds using ceric ammonium nitrate catalyst by a three component one-pot reaction. Structures of these compounds were established on the basis of infrared spectroscopy, proton nuclear magnetic resonance, carb...

Introduction Graft copolymerization is one of the most promising technique uses to modify the properties of naturally available polymers with a minimum loss in their native characteristics. Methods and Materials Graft copolymerization is a very significant technique to add hybrid properties in backbone of polymers. The grafting generally initiated through the formation of free radical centers...

Aim: The present study was intended to develop some novel imidazole derivatives via multi-component reaction catalysed by Ceric Ammonium Nitrate (CAN) in polyethylene glycol-400 (PEG-400) and its HMG-CoA reductase inhibitory activity for benefit in atherosclerosis. Methods: The one-pot synthesis has been achieved by taking benzyl, benzaldehyde, 3-amino-1, 2, 4triazole-5carboxylic acid (0.01 mol...

Homogeneous graft copolymerization of methyl methacrylate (MMA) onto cellulose was carried out in N, N – dimethyl acetamide/LiCl (DMAc/LiCl) and dimethyl sulfoxide/ paraformaldehyde (DMSO/PF) solvent system taking ceric ammonium nitrate (CAN), benzoyl peroxide (BPO) and tin (II)-2ethyl hexanoate [Sn(Oct)2] as initiators. Different grafting parameters like graft yield (GY), grafting efficiency (...

Pyrroloquinone ring systems are important structural units present in many biologically active molecules including a number of marine alkaloids. For example, they are found in a series of marine metabolites, such as tsitsikammamines, zyzzyanones, wakayin, and terreusinone. Several of these alkaloids have exhibited antimicrobial, antimalarial, antifungal, antitumor, and photoprotecting activitie...

Graft copolymerization of acrylamide (Am) onto rubberwood fibre (RWF) was carried out by free radical initiation. Ceric ammonium nitrate was used as an initiator system. The effects of temperature, dose of initiator, ratio of monomer to fibre, and nitric acid concentration, on the grafting percentage were investigated. The optimum reaction temperature was found to be about 50°C for 4h and with ...

Ethyl Acrylate was grafted onto chitosan by using the ceric ammonium nitrate as the initiator. The effect of initiator concentration, monomer concentration, time & temperature on % G and % E were studied. The grafted samples were characterized using FTIR, SEM, atomic force microscopy AFM and XRD methods. Xray diffraction showed changes in the crystallinity pattern of chitosan after the copolyme...
