Description:
An efficient and sustainable approach to rapid organic synthesis using ‘greener’ conditions, especially in the context of multi-component condensation reactions that are amenable to building libraries of compounds, is described. The use of solvent-free mechanochemical mixing, or microwave activation under a variety of benign reaction conditions such as neat reactants or solid supported catalysts, safer solvents (water, polyethylene glycol) is summarized to expeditiously assemble a diverse array of useful target molecules. Similar strategy for the generation of metallic or bimetallic nanomaterials in eco-friendly medium or in crosslinked form as nanocomposites will be presented that may find useful application in chemical synthesis.
