Abstract

Cyclohexan-1’,2’-dione-1’-diazabenzoic acids obtained from diazotised aminobenzoic acids and 2-hydroxymethylenecyclohexanone on cyclization afford 1-oxo-1,2,3,4-tetrahydrocarbazole derivatives. These on esterification followed by aromaisation and methylation gave the Mukonine isomers, 19, 20 and 22.
