An 1-amido-3-(2-hydroxyphenoxy)-2-propanol derivative represented by the following formula (1),
wherein cycle A may have further 1 to 4 substituents, and said substituent means a substituent selected from the group consisting of saturated or unsaturated C1-4 alkyl group, aralkyl group in which alkyl moiety has 1 to 4 carbon atoms, aryl group, halogen atom, halogenated C1-4 alkyl group, C2-5 alkanoyl group, mono or dialkylcarbamoyl group in which alkyl moiety has 1 to 4 carbon atoms, cyano group and nitro group, and the substituents at positions 3 and 6, or at positions 4 and 5 on the cycle A are different each other. Other ring may be fused at positions 3 and 4, or at positions 5 and 6 on the cycle A to form a condensed polycyclic hydrocarbon with the cycle A. R1 is alkanoyl group or aroyl group, and R2 is hydrogen atom, alkanoyl group or aroyl group, or R1 and R2 may be combined together with the N atom to form a cyclic imido group, which is useful as an intermediate of medicines, etc.
以下是由以下式子(1)表示的1-酰胺基-3-(2-羟基苯氧基)-2-丙醇衍生物,其中环A可能有进一步的1到4个取代基,所述取代基是从饱和或不饱和的C1-4烷基,烷基基团具有1至4个碳原子的芳基烷基基团,芳基基团,卤素原子,卤代的C1-4烷基基团,C2-5脂肪酰基基团,具有1至4个碳原子的单烷基或二烷基氨基基团,氰基和硝基的群中选择的取代基,且在环A的3和6位或4和5位处的取代基彼此不同。其他环可以与环A上的3和4位或5和6位融合,形成具有环A的缩合多环烃。R1是脂肪酰基基团或芳酰基基团,R2是氢原子,脂肪酰基基团或芳酰基基团,或R1和R2可以与N原子结合形成环状亚胺基团,可用作药物中间体等。
