The hitherto unknown Claisen rearrangement of 2-phenylsulfinyl-2-propenyl phenyl ethers to the corresponding 2-(2-phenylsulfinyl-2-propenyl)phenols is reported.The latter compounds underwent Michael reactions with a variety of nucleophiles to provide functionalized phenolic adducts.O-Alkylation of the initial rearrangement products with 3-bromo-2-phenylsulfinyl-1-propene and 2,3-dibromo-1-propene followed by sigmatropic rearrangement provided a promising route to 7-substituted 2-methylbenzofurans.
