Chiral oxazolidinone based hydrazides undergo efficient cross [2 + 2]-photocycloaddition upon visible light illumination. Oxazolidinone functionality acted as an energy harvesting photo-auxiliary. The cross [2 + 2]-photocycloaddition proceeded efficiently from the excited state with moderate to excellent isolated yield of the photoproduct. The photo-auxiliary can be conveniently removed post-photoreaction, which highlights the versatility of this strategy.
