A crossed coupling reaction of aromatic aldehydes with diethyl maleate by using phenylsilane and a catalytic amount of bis (dipibaloylmethanato) cobalt (II) were carried out to give an Alodol-type diethyl 2-(1-hydroxy-1-arylmethyl) succinates in modelate yields. These substituted diethyl succinates obtained were treated by refluxing in the presence of a catalytic amount of sulfuric acid to give the corresponding γ-arylbutyrolactones in 55〜60% yield. The reaction of γ-arylbutyrolactones with sodium ethoxyde in ethanol gave the half-ester arylmethylene succinate, and the reaction of the half-ester with a catalytic amount of potassium acetate in acetic anhydride gave the substituted naphthylesters.
