The batch reactions of cyclopropanols 1a and 1l with benzylidene malononitrile 2a have been successfully upscaled when translated into a continuous-flow process (Figure , a). Flow chemistry is especially advantageous for performing photochemical transformations, since it ensures more efficient light irradiation, consistency of results, and scalability among other benefits. Recently, TBADT recycling strategy by nanofiltration was developed by the group of Noёl, allowing to use TBADT-photocatalyzed reactions at industrial scale. After a brief optimization (see Tables and in the Supporting Information), we were able to prepare compounds 3aa and 3la in good 74-75% yields and gram amounts with 20-30 min of residence time.
