A protocol for the synthesis of three types of N‐heterocycles was developed. Cyclic enaminones were prepared under eco‐friendly conditions by photocatalyticdehydrogenation using rhodamine 6G as inexpensive photocatalyst and oxygen as the terminal oxidant. The method was extended to access azocinones by a [2+2] cycloaddition/ring‐expansion sequence in a one‐pot procedure.
