Abstract
1-Alkylamino-3-(2-(endobicyclo3.1.0!-hex-6-yl)ethylaminocarbonyl!naphthyl oxy)-2-propanols and methods for preparing these compounds are disclosed. The compounds are useful in the treatment of hypertension and abnormal heart conditions in mammals. These compounds are prepared by the treatment of the corresponding 1,2-epoxy-3-2-(endobicyclo3.1.0!hex-6-yl)ethylaminocarbonyl!naphthyloxy) -propane with an alkylamine having the desired alkyl substituent or by base or acid hydrolysis of the corresponding 2-optionally substituted -3-alkyl-5-(2-(endobicyclo3.1.0!hex-6-yl)ethylaminocarbonyl!naphthyloxym ethyl)oxazolidine. These latter compounds can be prepared by condensing a hydroxy-substituted naphthalene with a 3-alkyl-5-tosyloxymethyloxazolidine such substituted or unsubstituted at the 2-position or alternatively, by treating the former aminopropanol compounds of the present invention with an aldehyde having the desired substituent. These latter oxazolidine compounds are also active for treatment of hypertension and abnormal heart conditions.
