As an extension of the strong base-induced [4 + 2]cycloaddition of homophthalic anhydrides studied previously, we found a general and versatile synthesis of p-phenylthio substituted phenols by the reaction of 4-phenylthio-substituted homophthalic anhydrides and various dienophiles. The use of the sulfinyl-substituted dienophile is essential to produce the desired reaction under mild conditions in good yield.
