An Improved Protocol for Biginelli Reaction

Hmim][Tfa] was tested as catalyst for the Biginelli reaction multicomponent reaction under conventional and non conventional heat source i.e. Microwave heating. Low catalyst loading, reduced reaction time and operational simplicity are the main highlights of this proposed protocol. Using our proposed protocol, we tested 30 different biologically active compounds in good yield.

An Improved Junction-Based Directional Routing Protocol (IJDRP) for VANETs

Vehicular Ad-Hoc Networks (VANETs) is a novel technology that has recently emerged and due to its swift changing topology and high mobility nature, it has become problematic to design an efficient routing protocol in VANETs’ amongst both moving and stationary units. Also, the existing routing algorithms are not very effective to satisfy all requirements of VANETs. This paper explores the need o...

Biginelli Reaction Catalyzed by Copper Nanoparticles

We recently reported a novel synthesis of copper nanoparticles from copper sulphate utilizing the charge-compensatory effect of ionic liquid [bmim]BF(4) and ethylene glycol. The nanoparticles were characterized and found to be stable for one year. Here we hypothesize that the stabilized nanoparticles should be able to catalyze one-pot multicomponent organic reactions. We show that the nanoparti...

An Efficient Protocol for the Synthesis of Carboacyclic Nucleosides via Aza-Conjugate Addition Reaction

A new efficient method for the synthesis of carboacyclic nucleosides as biologically interesting compounds via aza-conjugate addition of pyrimidine nucleobases to a,β-unsaturated esters in the presence of catalytic amount of LiOH.H2O (1.2-4.8 mol%) under microwave irradiation is described. This method affords the title compounds in good to excellent yields and i...

Highly enantioselective Biginelli reaction catalyzed by SPINOL-phosphoric acids.

A highly enantioselective Biginelli reaction promoted by chiral spirocyclic SPINOL-phosphoric acids has been developed. Under the optimized conditions with 5 mol% catalyst loading, a wide range of optically active dihydropyrimidinethiones (DHPMs) were obtained in high yields (up to 98%) with good to excellent enantioselectivities (up to 99% ee). The synthetic utility of this method was demonstr...
