Studies in relation to biosynthesis. VI. Rheosmin

Abstract

Benzalpiperitone (I) has been dehydrogenated to 3-hydroxy-4-isopropylstilbene (II), which on ozonolysis gave rise to 3-hydroxy-4-isopropylbenzaldehyde (IV), which is unlikely to be identical with rheosmin. This substance appears on the basis of its properties and possible biosynthesis to be 1-(p-hydroxypheny1)butan-3-one (V).
