The application of microwave chemistry in organic synthesis has become increasingly common over the past few years. This technology has been employed to advance numerous drug discovery programs within AstraZeneca. Our interest in microwave-assisted organic synthesis has prompted us to investigate further the parameters that influence the efficiencies that have been observed with this technology. This presentation will highlight two areas of investigation. First, we will present our findings, within a series of 2,4-dialkylaminoquinolines, on thermal versus microwave reaction rates, and describe the effects of a variety of parameters such as solvent/reaction media, microwave power, and microwave pulsing. Secondly, we will illustrate the use of real-time in situ Raman analysis of microwave-assisted organic reactions.
