1-Amino-3-(4- or 5-substituted thiazol-2-oxy)-2-propanol and/or substituted amino derivatives thereof; 3-(4- or 5-substituted thiazol-2-oxy)-1,2-epoxypropane and 5-(4- or 5-substituted thiazol-2-oxymethylene)-oxazolidine and/or N- and/or 2-substituted oxazolidine derivatives thereof, and methods of making such compounds. The compounds are characterized by an aminocarbonyl or carbonylamino type substituent at the 5- or 4-position on the thiazole ring. The above 1-amino-3-(4- or 5-substituted thiazol-2-oxy)-2-propanol and derivatives exhibit cardiovascular activity and are useful in the treatment of abnormal heart conditions in mammals. The 3-(4- or 5-substituted thiazol-2-oxy)-1,2-epoxypropanes are useful as intermediates for the aforementioned cardiovascular agents. The 5-(4- or 5-substituted thiazol-2-oxymethylene)-oxazolidine and derivatives are intermediates for the aforementioned cardiovascular agents and further exhibit cardiovascular activity and thus are useful in the treatment of abnormal heart conditions in mammals. The 1-amino-3-(4- or 5-substituted thiazol-2-oxy)-2-propanol and derivatives can be prepared by base or acid hydrolysis of the corresponding 5-(4- or 5-aminocarbonylthiazol-2-oxymethylene)-oxazolidine or derivative; or by treatment of the corresponding 3-(4- or 5-substituted thiazol-2-oxy)-2,3-epoxypropane or derivative with the desired amine or amine derivative.
