An Improved Protocol for the Aldehyde Olefination Reaction Using (bmim) () as Reaction Medium

Preparation of Ag2S Nanoparticles and using as Catalyst for the A3-coupling (Aldehyde-Amine-Alkyne) Reaction

Microwave assisted facile one-step approach was adopted to prepare mono-dispersed silver sulfide nanoparticles. The structures of the synthesized Ag2S nanoparticles were confirmed by Fourier-transform infrared spectroscopy (FT-IR), diffuse reflectance UV-vis spectroscopy (DRS), X-ray diffractometer (XRD), energy dispersive X-ray analysis (EDX) and transmission electron microscope (TEM). The pre...

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.

Improved protocol for using avian red blood cells as substrates for the polymerase chain reaction.

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...

A Novel protocol for synthesis of Hantzsch 1, 4- dihydropyridines using PEG-400 as a reaction medium and under catalyst-free condition

An efficient and expeditious catalyst-free procedure was developed for the one- pot synthesis of 1, 4-dihydropyridine derivatives via the three-component reaction of various aldehydes, ethyl acetoacetate, and ammonium acetate in PEG-400. The reaction was carried out at 110°С and the products were obtained in good to high yields.
