Abstract
1,197,168. Tricyclic ketones. F. HOFFMANN-LA ROCHE & CO., A.G. 6 March, 1969 [15 March, 1968], No. 11865/69. Heading C2C. The invention comprises tricyclic ketones of the formula wherein R 1 , R 2 and R 3 represent H, halogen, OH, C 1-7 alkyl, C 1-7 alkoxy, C 1-7 alkylamino, NH 2 , di-(C 1-7 alkyl) amino, SH or C 1-7 alkylmercapto; R 4 and R 5 represent H, C 1-7 alkyl or alkoxy; R 6 represents H or C 1-7 alkyl, and R 7 and R 8 represent H or C 1-7 alkyl or alkoxy with the proviso that at least one of R 7 and R 8 is C 1-7 alkyl or alkoxy; and acid addition salts thereof. They may be obtained by heating a compound of the formula or a compound of the formula wherein R
