In chemistry a one-pot synthesisis a strategy to improve the efficiency of a chemical reaction whereby a reactant is subjected to successive chemical reactions in just one reactor. This is much desired by chemists because avoiding a lengthy separation process and purification of the intermediate chemical compounds would save time and resources while increasingchemical yield.An example of a one-pot synthesis is thetotal synthesis of tropinone or theGassman indole synthesis. Sequential one-pot syntheses can be used to generate even complex targets with multiple stereocentres, such asoseltamivir,[1] which may significantly shorten the number of steps required overall and have important commercial implications.
