Abstract
Aminomethyl-chromans are obtained by alkylation of correspondingly substituted amines or by reductive amination of correspondingly substituted aldehydes. The aminomethyl-chromans can be used as active compounds in medicaments, in particular for the treatment of diseases of the central nervous system.
Claims14
Aminomethyl-chromans of the formula ##STR184## in which A, B and D are identical or different and represent hydrogen, halogen, cyano, azido, nitro, difluoromethyl, trifluoromethyl, difluoromethoxy, trifluoromethoxy, hydroxyl or carboxyl, or represent straight-chain or branched alkyl, alkenyl, acyl or alkoxycarbonyl having in each case up to 8 carbon atoms, or represent a group of the formula --NR.sup.2 R.sup.3, --NR.sup.4 --L--R.sup.5 or --OR.sup.6, wherein
- R.sup.2, R.sup.3 and R.sup.4 are identical or different and denote hydrogen, straight-chain or branched alkyl having up to 8 carbon atoms, phenyl or benzyl,
- L denotes the --CO-- or --SO.sub.2 -- group,
- R.sup.5 denotes straight-chain or branched alkyl having up to 8 carbon atoms or benzyl, or denotes aryl having 6 to 10 carbon atoms, which is optionally substituted by halogen, hydroxyl, nitro, cyano, trifluoromethyl or trifluoromethoxy or by straight-chain or branched alkyl or alkoxy having in each case up to 6 carbon atoms and
- R.sup.6 denotes straight-chain or branched alkyl or alkenyl having in each case up to 8 carbon atoms, which are optionally substituted by cycloalkyl having 3 to 6 carbon atoms or phenyl,
- or
- A has one of the abovementioned meanings and
- B and D together form a 5- or 7-membered saturated partly unsaturated or aromatic carbocyclic ring optionally substituted by up to 2 identical or different substituents selected from the group consisting of straight-chain or branched alkyl and alkoxy having in each case up to 6 carbon atoms, hydroxyl, cycloalkyl having 3 to 6 carbon atoms, phenyl, halogen, cyano and nitro, or in spiro form by a radical of the formula ##STR185## wherein m denotes the number 1 or 2, E represents a direct bond, or represents straight-chain or branched alkylene, alkenylene or alkinylene having in each case up to 10 carbon atoms, which are optionally substituted by phenyl,
- G represents a cycloalkyl ring having 3 to 15 carbon atoms, where all the cyclic rings are optionally substituted by up to 3 identical or different substituents, selected from the group consisting of halogen, hydroxyl, nitro, cyano, difluoromethyl, trifluoromethyl, difluoromethoxy and trifluoromethoxy and straight-chain or branched alkyl and alkoxy having in each case up to 8 carbon atoms, the latter optionally being substituted by phenyl or phenoxy, and
- R.sup.1 represents hydrogen or represents straight-chain or branched alkyl having up to 8 carbon atoms, or represents the radical of the formula --E', --G', wherein E' and G' have the meaning given above for E and G and are identical to or different from these radicals,
- or an isomer or salt thereof.
