Abstract
1333564 Bridged-ring isoquinoline derivatives UCB SA 22 Oct 1971 [22 Oct 1970] 50214/70 Heading, C2C The invention comprises (with exceptions as to certain methyl-substituted compounds, as defined in the Specification) compounds of formula wherein R 1 to R 5 are each H, alkyl, hydroxyalkyl, aminoalkyl, alkylaminoalkyl, dialkylamino, alkenyl, aryl or aralkyl, and R 6 is H, halogen, CF 3 , alkyl oralkoxy; each alkyl, alkenyl oralkoxy group containing up to 4 carbon atoms. These compounds are prepared by first forming a compound of formula by Diels-Alder addition of a maleic anhydride to a 3 - oxo - 1,2,3,4 - tetrahydroisoquinoline, hydrolysing it to the corresponding dicarboxylic acid, oxidatively decarboxylating the latter and optionally N-substituting the product (when R 1 =H).
