Résumé
We describe herein an unprecedented mechanochemical "parallel synthesis'' of 3,4-dihydro-2H-benzo[e][1,3] oxazine derivatives via a one pot three component reaction. The new milling system uses a multiposition jar (variable sizes are possible), allowing for the processing of up to 12 samples simultaneously, leading to the formation of a fungicide and a building block for polymer preparation with higher throughput compared to standard milling devices.
