Several new compounds were obtained as degradation products from a new substance from yeast during the elucidation of its structure as 2-(6-hydroxy-2-methoxy-3, 4- methylenedioxyphenyl)-benzofuran. The structures of these new degradation products were proved by synthesis and are: 1, 5-dimethoxy-2, 3-methylenedioxybenzene(VII), 5-ethoxy-1- niethoxy-2, 3-methylenedioxybenzene (IX), l-ethoxy-5-methoxy-2, 3- ...
