Process for the preparation of 5,6-dihydropyrrolo [2,1-a] isoquinoline derivatives containing functional group in position 2

The invention pertains to a novel method for the synthesis of 5,6-dihydropyrrolo [2,1-a] isoquinoline derivatives containing a functional group in position 2. The method consists of dissolving 6,7-diethoxy-3,4-dihydro-1- (3,4-diethoxybenzoyl) isoquinoline in trifluoroethanol and adding acrolein or crotonaldehyde or cinnamaldehyde or acrylonitrile and stirring at a temperature of + 70 ° C. The residue obtained after completion of the reaction and removal of the reagents is crystallized in a mixture of ether and hexane. The proposed process allows the preparation of 2-functionally substituted 5,6-dihydropyrrolo derivatives by acrolein or crotonaldehyde or cinnamic aldehyde or acrylonitrile to 6,7-diethoxy-3,4-dihydro-1- (3,4-diethoxybenzoyl) isoquinoline in trifluoroethanol [2,1-a] isoquinolines.
