Synthesis of substituted benzofurans via microwave-enhanced catch and release strategy.
A microwave-enhanced procedure for the synthesis of substituted benzofurans starting from 2-(1-hydroxyalkyl)-phenols and using triphenylphosphine polystirene resin is reported. The benzofurans are isolated in good to high yields and purities by simple workup. The procedure can be applied to chiral alpha-alkyl-2-benzofuranmethanamines too.
