| titleOfInvention | 4-amino-trans-decahydroquinoline derivatives |
| abstract | 1515540 4 - Amino - trans - decahydroquinoline derivatives LABAZ 24 Nov 1976 [16 Dec 1975] 51507/75 Heading C2C Novel trans decahydroquinoline derivatives of the Formula I and pharmaceutically acceptable acid addition salts thereof, wherein R1 is alkyl, alkoxy, dialkylamino, a saturated heterocyclic ring attached through a ring nitrogen atom, an unsaturated heterocyclic group or an optionally substituted phenyl, R2 is alkyl, optionally substituted phenyl, naphthyl, unsaturated heterocyclic optionally substituted by alkyl, aralkyl, aralkenyl or alicyclic and R3 is alkyl substituted furyl, aralkyl, aralkenyl or a group where A is C 1-4 -alkylene, Y is oxygen, sulphur, carbonyl > C = NOH, >C = NNH 2 or sulphoxide or a group X R4 and R5 each are hydrogen, halogen, methyl, methoxy or acetyl and n is zero or 1, with the proviso that when n is zero, Y is carbonyl, where alkyl groups unless otherwise specified have 1 to 4 carbon atoms, may be prepared, when R 1 is other than dialkylamino or saturated heterocyclic group attached by a ring nitrogen atom and when R3 is a group II, Y is other than hydroxyiminomethylene or hydrazonomethylene by reacting a compound III with R1COCl or (R1CO) 2 O or when R1 is dialkylamino or a saturated heterocyclic group attached by a ring nitrogen atom, and when R3 is a group II, Y is other than hydroxyiminomethylone or hydrazonomethylene by reacting a compound VI with an amine R1H, optionally followed by acid addition salt formation and/or reacting a carbonyl at Y with hydroxylamine or hydrazine to form a hydroxylimino methylene or a carbonyl hydrazonomethylene. Intermediates of the Formula III are prepared by reacting 4-oxo-trans-decahydroquinoline with an amine R2NH 2 and reducing the imine so formed to produce a compound VIII which is reacted with R3-Hal, where Hal is chlorine, bromine or iodine. When R3 is a group II and Y is carbonyl, the carbonyl group is protected with a group X and thereafter optionally hydrolysed. The isomers of the compound VIII are separated. Pharmaceutical compositions of the compounds I with the usual excipients show analgesic activity when administered orally, parenterally or rectally. The compounds I in which R1 is alkoxy also show antihypertensive action. |
