The present invention relates to new naphthyl derivatives of general formula ##STR1## wherein N represents the number 1 or 2, A represents a --CH.sub.2 --, --CO--, --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, ##STR2## while the atom marked with an x is linked to the phenyl nucleus, E represents a straight chained alkylene group optionally substituted by an alkyl group, G represents a straight chained alkylene group optionally substituted by an alkyl group, L represents a bond or an oxygen atom, if G represents a straight chained alkylene group with 2 to 5 carbon atoms optionally substituted by an alkyl group, R.sub.1 and R.sub.2, which may be identical or different, represent alkyl or alkoxy groups or R.sub.1 and R.sub.2 together represent an alkylenedioxy group, R.sub.3 represents a hydrogen atom, or an alkyl or an allyl group, R.sub.4, R.sub.5 and R.sub.6, which may be identical or different, represent hydrogen atoms, alkyl or alkoxy groups, the enantiomers and the acid addition salts thereof, which have valuable pharmacological properties, particularly a heart rate lowering activity. The new compounds may be prepared using methods known per se.
本发明涉及新的萘基衍生物,其一般式为##STR1##其中N代表1或2,A代表--CH.sub.2 --、--CO--、--CH.sub.2 CH.sub.2 --、--CH.dbd.CH--、##STR2##而带有x标记的原子连接到苯环,E代表一直链烷基,可选择地被烷基取代,G代表一直链烷基,可选择地被烷基取代,L代表键或氧原子,如果G代表一直链烷基,其具有2至5个碳原子,可选择地被烷基取代,R.sub.1和R.sub.2,可以相同或不同,代表烷基或烷氧基,或者R.sub.1和R.sub.2一起代表烷二醇基,R.sub.3代表氢原子,或烷基或烯丙基,R.sub.4、R.sub.5和R.sub.6,可以相同或不同,代表氢原子、烷基或烷氧基,其对映异构体和酸加成盐具有有价值的药理学性质,特别是降低心率的活性。新化合物可以使用已知的方法制备。
