Phenylbutanol derivatives of the formula Z--C(CH.sub.3) (OH)--CH.sub.2 --Y wherein Z is 4-biphenyl or 4-phenoxyphenyl wherein the phenoxy group is unsubstituted or substituted by F, Cl or Br and Y is COOR.sup.2 or CH.sub.2 OR.sup.3 wherein R.sup.2 is H or alkyl of 1 to 6 carbon atoms and R.sup.3 is H or alkanoyl of 1 to 6 carbon atoms, and their physiologically acceptable salts, possess anti-inflammatory activity and are produced by (a) treating with a solvolyzing agent a compound of the formula Z--C(CH.sub.3) (OH)--CH.sub.2 --W or Z--CX(CH.sub.3)--CH.sub.2 --Y wherein W is a functionally modified carboxy or methylol group different from Y and X is Cl, Br or I or a functionally modified hydroxyl group; or (b) reducing a compound otherwise corresponding to a desired final product but having instead of one of the hydrogen atoms a group which can be reduced or replaced by a hydrogen atom; or (c) oxidizing a compound otherwise corresponding to a desired final product but lacking the tertiary hydroxyl group; or (d) converting a compound otherwise corresponding to a desired final product wherein Z is a 4-phenoxyphenyl group but having instead a 4--OH--, Cl--, Br-- or I-substituted phenyl group into a desired final product; or (e) diazotizing a compound otherwise corresponding to a desired final product wherein Z is a halogen-substituted 4-phenoxyphenyl group but having an --NH.sub.2 -substituted phenoxy group and reacting the resulting diazonium salt with a halogenating agent.
公式为Z--C(CH.sub.3) (OH)--CH.sub.2 --Y的苯基丁醇衍生物,其中Z为4-联苯或4-苯氧基苯,其中苯氧基未取代或被F、Cl或Br取代,Y为COOR.sup.2或CH.sub.2 OR.sup.3,其中R.sup.2为H或1至6个碳原子的烷基,R.sup.3为H或1至6个碳原子的烷酰基,以及它们的生理上可接受的盐,具有抗炎活性,并通过(a)用溶解剂处理公式为Z--C(CH.sub.3) (OH)--CH.sub.2 --W或Z--CX(CH.sub.3)--CH.sub.2 --Y的化合物,其中W是与Y不同的功能修饰的羧基或甲醇基,X为Cl、Br或I或功能修饰的羟基;或(b)还原化合物,该化合物与所需的最终产物相对应,但其中一个氢原子的位置被还原或替换为氢原子;或(c)氧化化合物,该化合物与所需的最终产物相对应,但缺少三级羟基;或(d)将化合物转化为所需的最终产物,其中Z为4-苯氧基苯基,但取而代之的是4-OH-,Cl-,Br-或I-取代的苯基;或(e)重氮化化合物,该化合物与所需的最终产物相对应,其中Z为卤代的4-苯氧基苯基,但具有--NH.sub.2-取代的苯氧基,并将所得的重氮盐与卤代试剂反应。
