Abstract
Ethyl esters of 2-carboxylic acids of 3H,10H-indeno[2,1-e]-1H,9H-indeno[1,2-f]indoles and their keto derivatives were obtained on the basis of 2-aminofluorene and its 9-keto derivative via the Japp-Klingemann and Fischer reactions. Saponification with subsequent decarboxylation of these products leads to unsubstituted cyclic systems and their keto derivatives.
