The invention relates to a morpholine derivative oxidation ring-opening method and a product thereof, and belongs to the technical field of compound preparation. The method for promoting oxidative cracking of C (sp3)-C (sp3) bonds of a morpholine derivative by visible light has been successfully developed under the inspiration of the design concept of visible light induced C (sp3)-C (sp3) bond cracking. According to the morpholine derivative oxidation ring-opening method, C (sp3)-C (sp3) bonds without ring stress are cracked by using visible light as an energy source and O2 as a final oxidizing agent, use of transition metal, high temperature, high pressure and chemical equivalent dangerous oxidizing agents is avoided, good functional group tolerance is established, 30 substrates are obtained, the yield is as high as 83%, and a supplementary scheme is provided for realizing oxidative cracking of the morpholine derivative under a mild condition.
