unprecedented cross-coupling reaction between copper carbene and nitroso radical has been developed. This radical-carbene couplingreaction (RCC reaction) offers a novel approach for the preparation of various isoxazolines, which features the construction of C–C, C–O, and C═N bonds in a one-pot process. The synthetic utility of our method is further enhanced by its mild reaction conditions, wide substrate
