Abstract

AbstractThe reaction of homophthalic anhydride and N‐(1‐methyl‐1H‐pyrrol‐2‐yl‐methylidene)‐benzylamine in boiling benzene afforded as a main product the expected substituted trans‐1,2,3,4‐tetrahydroisoquinoline‐4‐carboxylic acid 5. The carboxylic group of 5 was transformed in four steps into cyclic amino‐methyl groups yielding numerous new tetrahydroisoquinolinones 11a‐j incorporating a given fragment of pharmacological interest. Reduction of 11a‐j was studied.
