Paragraph 0044-0061; 0091-0094, (2020/01/12)
The invention discloses a green synthesis method of an N-substituted-1,4-dihydro-2,3-quinoxalinedione compound. The green synthesis method comprises the following steps: reacting ammonium persulfate with an N-substituted quinoxaline-2(1H)-one derivative in an aqueous solution of DL-alpha-tocopherol methoxy polyethylene glycol succinic acid water to generate the N-substituted-1,4-dihydro-2,3-quinoxalinedione compound; and after the reaction is finished, extracting a reaction product by using ethyl acetate, and performing vacuum drying to obtain the high-purity target product. The aqueous solution of the DL-alpha-tocopherol methoxy polyethylene glycol succinic acid can be recycled at least five times or more. The method is good in product selectivity, high in yield, simple in separation process, low in raw material cost, friendly to environment and beneficial for industrial production and application.
