Synthesen von Nitrophenanthrencarbonsäuren mit konstitutioneller Beziehung zu den natürlichen Aristolochiasäuren

摘要

The synthesis of various methoxy- and methylenedioxy-substituted nitrophenanthrene carboxylic acids is described. Some of the substances cause an increase in the phagocytic activity of leucocytes as has been established for natural aristolochia acid-I.
