Paragraph 0011; 0013; 0014, (2018/05/30)
The invention relates to a method for synthesizing 1,2,3,4-tetrahydroquinoline compounds in the mode that decarboxylation of amino acid is catalyzed by visible light. The method is characterized in that in an air atmosphere, the N-phenyl amino acidic compounds shown in the formula I, an organic photocatalyst DPZ and 4-molecular sieve are dissolved in an organic solvent, stirred and reacted for atleast 5 hours at the temperature of 20-30 DEG C under the irradiation of the visible light, separation and purification are conducted, and then the tetrahydroquinoline compounds shown in the formula II are obtained, wherein in the formula I and the formula II (the formulas are shown in the description), R is representative for any one of hydrogen, halogen, alkyl, phenyl and alkoxy, R1 is representative for any one of hydrogen, methyl, n-propyl and phenyl, alkyl is representative for methyl or ethyl or normal-butyl or benzyl, and aryl is representative for substituted phenyl or 4-tert-butyl phenyl. According to the method, substrates are simple, reaction conditions are mild, the usage amount of the catalyst is low, the yield is high, and no metal participates in a reaction.
