Abstract
1364806 Substituted tricyclic furans and thiophenes F HOFFMANN-LA ROCHE & CO AG 24 March 1972 [26 March 1971] 13877/72 Heading C2C Novel compounds of the Formula I wherein R 1 and R 2 are independently hydrogen, halogen, C 1-7 alkyl, C 1-7 alkoxy, C 1-7 alkylthio, trifluoromethyl, cyano, carbamoyl, carboxy, C 1-7 alkoxycarbonyl, nitro, amino, mono-(C 1-7 alkyl) amino, di-(C 1-7 alkyl) amino, acyl, acylamido, sulphamoyl, di-(C 1-7 alkyl) sulphamoyl, or difluoromethylsulphonyl; R 3 is hydrogen, C 1-7 alkyl, amino-C 1-7 alkyl, mono-(C 1-7 alkyl) amino-C 1-7 alkyl, di-(C 1-7 alkyl) amino C 1-7 alkyl; n is 1 or 2 and X is oxygen or sulphur, may be prepared by (a) cyclizing a compound of the formula II wherein at least one position on the phenyl ring ortho to X is unsubstituted, and R<SP>1</SP> 3 is C 1-7 alkyl, (b) treating a compound IIa wherein R<SP>1</SP> 1 and R<SP>1</SP> 2 are independently hydrogen, nitro, trifluoromethyl, C 1-7 alkoxycarbonyl, cyano or acyl (at least one of R<SP>1</SP> 1 and R<SP>1</SP> 2 being other than hydrogen) with an acidic catalyst to yield an appropriate substituted compound I in which X is oxygen, and (c) interconversion of substituents on I by known methods and separation of isomers, i.e. resolution, conversion to a salt with acid or base, saponification of a carboxylic ester group, conversion of a salt of compound I wherein R 3 represents hydrogen into a compound I wherein R 3 represents other than H or alkyl, reduction of a nitro to an amino group, conversion of an amino group into a diazonium salt and thence into hydrogen, halogen, cyano, hydroxy or alkoxy. Compounds of Formula IIa above are prepared by reacting compounds and Cycloalkanes of Formula IV are obtained by halogenating the corresponding halogen free compound. Pharmaceutical compositions having antiinflammatory and anti-rheumatic activity and which are useful for oral, enteral or parenteral administration, contain the above novel compounds I.
