Studies on the Structure of Serpentinine. V

Synthesis of Compound C (Flavopereirine) and Compound D (Dihydroflavopereirine), and the Probable Structure of Serpentinine

Abstract

Compound C (flavopereirine) and Compound D (dihydroflavopereirine), isolated from the products of dehydrogenation of serpentinine, were synthesized and proved to be 3-ethylindolo [2, 3-a] quinolizinium base and 3-ethyl-6, 7-dihydroindolo [2, 3-a] quinolizinium base, respectively. All the findings described in the present and the preceding papers are in good agreement with the bimolecular formula (X) for serpentinine.
