Unlike 2-(3,4-dihydro-6-methoxy-1-naphthyl)ethenol acetate (I) [4-(2-acetoxyvinyl)-1,2-dihydro-7-methoxy-naphthalene], the diene of analogous structure -1,2-dihydro-7-methoxy-4-vinylnaphthalene (III)-in condensation with 3,5-dimethyl-3-cyclopentene-1,2-dione (II) forms an adduct (IV) which contains a 15- and not a 17-keto group. The orientation in the diene condensation is determined by the presence, or absence, of an electronegative substituent in the 1-position of the diene of type (III).
