| abstract | Processes for preparing 3-(4- or 5-substituted thiazol-2-oxy)propanediol 1,2-acetonides. The processes are characterized by the steps of treating the desired lithium salt of 3-(4- or 5carboxy-thiazol-2-oxy)-propanediol 1,2-acetonide with an alkyl chloroformate to yield the corresponding 4''-or 5''alkylcarbonyldioxycarbonyl derivative which is then reacted with an alkali metal azide to yield the corresponding 3-(4- or 5azidocarbonylthiazol-2-oxy)-propanediol 1,2-acetonide. The azidocarbonyl derivative can be readily rearranged to the isocyanato derivative which is an intermediate for cardiovascular agents useful for the treatment of mammals. |
