Photocatalytic coupling of aldehydes and silicon amine protocol (SLAP) reagents enables the simple, scalable synthesis of substituted morpholines, oxazepanes, thiomorpholines, and thiazepanes under continuous flow conditions. Key to the success of this process is the combination of an inexpensive organic photocatalyst (TPP) and a Lewis acid additive, which form an amine radical cation that is easily
