Ulein’in Total Sentezine Giriş

Abstract

In this part of the study of total synthesis ulein, 3-ethyl-1,2,3,4-tetrahydrocarbazole (1) has been obtained from phenylhydrazinium hycrochloride with 4-ethylcyclohexanon in the atmosphere of nitrogen. 3-Ethyl-1-oxo-1,2,3,4-tetrahydrocarbazole (2) has been synthesized from the reaction of oxidation of 3-ethyl-1,2,3,4-tetrahydrocarbazole (1). The structures of these compounds were determined by IR-, 1H-NMR spectroscopic data and elemental analysis
