In the Conventional laboratory or industry heating technique involve Bunsen burner, heating mental/hot plates and electric heating ovens. To produce a variety of useful compounds for betterment of mankind, the Microwave Chemistry was introduced in year 1955 and finds a place in one of the Green chemistry method. In Microwave chemistry is the science of applying microwave radiation to chemical reactions. Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid. Polar solvents are heated as their component molecules are forced to rotate with the field and lose energy in collisions i.e. the dipole moments of molecules are important in order to proceed with the chemical reactions in this method. It can be termed as microwave-assisted organic synthesis (MAOS), Microwave-Enhanced Chemistry (MEC) or Microwave-organic Reaction Enhancement synthesis (MORE). Microwave-Assisted Syntheses is a promising area of modern Green Chemistry could be adopted to save the earth.

Isatin Derivatives

Microwave-assisted organic synthesis, a green chemistry approach, is nowadays widely used in the drug synthesis. Microwave-assisted synthesis improves both throughput and turnaround time for medicinal chemists by offering the benefits of drastically reduced reaction times, increased yields, and pure products. Schiff bases are the important class of organic compounds due to their flexibility, and structural diversities due to the presence of azomethine group which is helpful for elucidating the mechanism of transformation and rasemination reaction in biological system. This novel compound could also act as valuable ligands for the development of new chemical entities. In the present work, some Schiff bases of Isatin derivatives was synthesized using microwave heating method. Schiff base of Isatin were synthesized by condensation of the keto group of Isatin with different aromatic primary amines. They were characterized by means of spectral data and subsequently subjected to the in vitro antibacterial activities against gram positive and gram negative strains of microbes. It was observed that the compound with electron withdrawing substituents exhibited good antibacterial activities against almost all the micro organisms.

: The chemistry of 2-quinolones derivatives has received more attention in the field of both organic chemistry and medicinal chemistry. As several advances in the application of this important family of compounds seem too significant utility. In recent years, a variety of new, effective, and novel synthetic approaches (including green chemistry, catalyzed and microwave-assisted synthesis) have been discovered and developed for the designer of various 2-quinolone-based scaffolds, representing an area of increased interest to universities and industry, as well as, to explore their antibacterial activities and reduced toxicity than the existing ones. This review summarizes the results of the literature on the synthesis strategies of 2-quinolones derivatives and their reactivity, as well as their antibacterial evaluations against different bacteria strains.

Heterometallic metal sulphur assemblies containing coinage metals and molybdenum as well as tungsten have already been studied in prebiotic condition of H2S and carcinogenic solvent like DMSO and DMF. Recently an attempt has been made to study the similar system under eco-friendly system using green–chemistry technique. The products were characterized on the basis of chemical and spectroscopic studies under a mimicking approach to a synthetic model system relevant to copper-molybdenum antagonism.
