Synthesis of 2-hydroxymethyl-2,3-dihydrobenzofurans

Chang, Meng-Yang,Lin, Shin-Ying,Chanp, Chieh-Kai

, p. 1905 - 1912 (2014/08/18)

A one-pot protocol toward 2-hydroxymethyl-2,3-dihydrobenzofurans (1) starting with oxygenated o-allylbenzaldehydes (3) was described. The facile one-pot process was carried out by the oxidation of o-allylbenzaldehydes (3) with Oxone in the co-solvent of acetone and DMF in the presence of aqueous EDTA solution and then intramolecular ring-closure of the resulting o-allylphenols (2) in acceptable yields.
