Zhang, Yin Jun,Wang, Yu Guang
experimental part, p. 212 - 216 (2012/07/13)
A very efficient solid-phase synthesis of substituted benzofuran using polymer-supported selenium resin is described. The advantages of the new method are good yields, high purity, straightforward operations, broad range and high diversity of products, lack of odor, and good stability of the resins. The easy work-up procedure makes the method suitable for building parallel libraries.

A tin(IV) chloride assisted iodo-cyclization of 2-allylphenol gave 2-iodomethyl-2,3-dihydrobenzofuran. A similar cyclization of 2-crotylphenol gave 3-iodo-2-methyl-3,4-dihydro-2H-benzopyran, exclusively. By iodination with mercury(II) oxide-iodine reagent in dichloromethane, 2,3-dihydrobenzofurans or 3,4-dihydro-2H-benzopyrans including the above benzocyclic ethers were easily converted to the corresponding 5- or 6-iodo derivatives, regioselectively, in good yield.
