Several new compounds were obtained as degradationproducts 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 degradationproducts were proved by synthesis and are: 1,5-dimethoxy-2,3-methylenedioxybenzene ( V I I ) , 5-ethoxy-1-niethoxy2,3-methylenedioxybenzene ( IX), l-ethoxy-5-methoxy-2

The reaction of spiroepoxycyclohexadienones 1 with TMSCN in the presence of catalytic amounts of Bu4NCN results in the formation of two diastereomeric cyanohydrins. Alternatively, the reaction of 1 with equimolecular amounts of Bu4NCN gave rise to products arising from two other different reaction paths.
