Green synthetic approaches are emerged as a remarkable technology for the production of biopolymer based novel derivatives. Microwave assisted synthesis method is considered as safe alternative to conventional physiochemical methods due to its environmental friendly nature.

Chitosan was derivatized with epichlorohydrin, asparagine using microwave. After this the product was regenerated from the mixture of water and methanol (1: 1)then washed with ethanol, methanol. Solvents like DMSO, DMF are used while synthesis. The characteristics of newly formed derivative was studied by Fourier transform Infrared spectrum(FT-IR), Thermogravimetric analysis(TGA), Nuclear Magnetic Resonance(NMR), Mass spectra, Scanning Electron Microscopy(SEM), elemental analysis etc. Antimicrobial activity was studied on different bacteria and fungi by well diffusion method.
