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. R
1
is alkanoyl group or aroyl group, and R
2
is hydrogen atom, alkanoyl group or aroyl group, or R
1
and R
2
may be combined together with the N atom to form a cyclic imido group, which is useful as an intermediate of medicines, etc.
由以下公式(1)表示的1-酰胺-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,含有1到4个碳原子的芳基烷基,芳基,卤素原子,卤代C1-4烷基,C2-5烷酰基,单或二烷基氨基基,其中烷基部分含有1到4个碳原子,氰基和硝基中选择的取代基,并且在环A上的位置3和6,或在位置4和5上的取代基彼此不同。其他环可能在环A上的位置3和4,或在位置5和6上与环A融合,形成与环A的紧缩多环碳氢化合物。R1是烷酰基或芳酰基,R2是氢原子,烷酰基或芳酰基,或R1和R2可以与N原子结合在一起形成环亚胺基团,可用作药物等的中间体。
