ls 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-l-propene followed by [3,3] sigmatropic rearrangement provided a promising route to 7-substituted 2-methylbenzofurans.
