An approach based on a highly controlled continuous‐flow (CF) retro‐Diels–Alderreaction was developed for the synthesis of new compounds. Using this approach, we were able to rapidly screen reaction conditions to obtain the desired pyrimidinone moieties in short reaction times and high yields. We also present an alternative route for the synthesis of intermediates by CF cyclization.
