1-Alkylamino-3-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxy)-2-propanol; 5-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxymethylene-N-alkyloxazolid ine and/or 2-substituted oxazolidine derivatives thereof, and methods of making such compounds. The compounds exhibit cardiovascular activity and are useful in the treatment of abnormal heart conditions in mammals. The compounds are also useful in the treatment of hypertension in mammals. The 5-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxymethylene)-N-alkyloxazoli dines and derivatives are also intermediates for the 1-alkylamino-3-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxy)-2-propanol s. The 1-alkylamino-3-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxy)-2-propanol s can be prepared by base or acid hydrolysis of the corresponding 5-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxymethylene)-N-alkyloxazoli dine or derivative; or by treatment of the corresponding 3-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxy)-2,3-epoxypropane with the desired alkylamine. Similarly the 5-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxymethylene)-N-alkyloxazoli dine or derivative can be prepared from the corresponding 1-alkylamino-3-(5-carbocyclicalkylaminocarbonylthiazol-2-yloxy)-2-propanol s via treatment with an aldehyde or ketone.
1-烷基氨基-3-(5-环烷基氨基甲酰基噻唑-2-氧基)-2-丙醇;5-(5-环烷基氨基甲酰基噻唑-2-氧甲基-N-烷氧噁唑啉和/或其衍生物,以及制备这些化合物的方法。这些化合物具有心血管活性,可用于治疗哺乳动物的异常心脏病症。这些化合物还可用于治疗哺乳动物的高血压。5-(5-环烷基氨基甲酰基噻唑-2-氧甲基)-N-烷氧噁唑啉和其衍生物也是1-烷基氨基-3-(5-环烷基氨基甲酰基噻唑-2-氧基)-2-丙醇的中间体。1-烷基氨基-3-(5-环烷基氨基甲酰基噻唑-2-氧基)-2-丙醇可以通过相应的5-(5-环烷基氨基甲酰基噻唑-2-氧甲基)-N-烷氧噁唑啉或其衍生物的碱性或酸性水解制备;或通过用所需的烷基胺处理相应的3-(5-环烷基氨基甲酰基噻唑-2-氧基)-2,3-环氧丙烷得到。同样,5-(5-环烷基氨基甲酰基噻唑-2-氧甲基)-N-烷氧噁唑啉或其衍生物可以通过与醛或酮处理相应的1-烷基氨基-3-(5-环烷基氨基甲酰基噻唑-2-氧基)-2-丙醇制备。
