Studies in the Cyclohexane Series. Part XIII. : Synthesis of Some Substituted 1,2,3,4-Tetrahydro-acridones and phenanthridones and N-Aryl-5-methyl 2,3,4,5,6,7- hexahydroindol-2-ones

Department of Chemistry, University of Delhi, Delhi-110007 Manuscript received 28 November 1974; revised 2 April 1975; accepted 29 April 1975 Ethyl 4-methyleyclohexan-1-one-2-carboxylate is condensed with a number of primary aromatic amines at room temperature and 180°-190° to give anils and anilides, which on cyclisation furnish substituted 1,2,3,4-tetrabydro-acridones and -phenanthridones. 4-Methylcydohexan-1-one-2-acetic acid is also condensed with a number of primary aromatic amines to give N-aryl-5-methyl-2,3,4,5,6, 7-hexahydroindol-2-ones
