Commercially available tin amine protocol (SnAP) reagents provide a simple approach to the synthesis of a wide variety of saturated N-heterocycles fromaldehydes. In this report, we disclose that the copper(II) promoter and hexafluoroisopropanol can be replaced by photocatalytic conditions using Ir[dF(CF3)ppy]2(dtbbpy)PF6 in CH3CN. Continuous flow photochemical conditions provide a clean, scalable
