Novel 3-Z-9-benzoyl-1,2,3,4-tetrahydrocarbazoles, wherein Z is CONR.sub.5 R.sub.6, CONHOH, CN, or COCH.sub.2 X, where X is chloro or bromo, having antimicrobial and/or anti-inflammatory activity are disclosed. Compounds wherein Z is CONR.sub.5 R.sub.6 and CONHOH are prepared from the corresponding 3-carboxylic acids by conversion to the corresponding acid chlorides and subsequent reaction with the appropriate amines and hydroxylamine respectively; compounds where Z is CN are prepared by the dehydration of the corresponding compounds where Z is CONH.sub.2 ; and the compounds where Z is COCH.sub.2 X are prepared by reacting hydrogen chloride or bromide with the corresponding compounds where Z is COCHN.sub.2 which in turn is prepared from the corresponding 3-carboxylic acid chloride by reaction with diazomethane.
本发明涉及一种Novel 3-Z-9-苯甲酰基-1,2,3,4-四氢咔唑,其中Z为CONR.sub.5 R.sub.6,CONHOH,CN或COCH.sub.2 X,其中X为氯或溴,具有抗微生物和/或抗炎活性。其中Z为CONR.sub.5 R.sub.6和CONHOH的化合物是通过将相应的3-羧酸转化为相应的酸氯化物,然后与适当的胺和羟胺分别反应制备的;其中Z为CN的化合物是通过脱水相应的Z为CONH.sub.2的化合物制备的;而Z为COCH.sub.2 X的化合物是通过氯化氢或溴化氢与相应的Z为COCHN.sub.2的化合物反应制备的,而后者又是通过将相应的3-羧酸氯化物与重氮甲烷反应制备的。
