Synthesis of salicylaldehydes from phenols via copper-mediated duff reaction

A copper-mediated Duff reaction for ortho-selective formylation of phenols has been developed. In the presence of copper species, significant improvements of yield and ortho-selectivity of the Duff formylation were achieved, which provides an easy access to salicylaldehydes from phenols.

A novel selective oxidation of 5-substituted 2-hydroxy-3-hydroxymethylbenzaldehydes

5-Substituted 2-hydroxy-1,3-benzenedicarbaldehydes 3 and 5-substituted 3-formyl-2-hydroxbenzoic acids 4 were prepared by selective oxidation of 5-substituted 2-hydroxy-3-(hydroxymethyl)-benzaldehydes 1 in a one-pot reaction. Compounds 1 were reacted with ethylenediamine and copper acetate to produce the complexes 2 as intermediates, in which formyl and phenolic hydroxy groups were protected in the subsequent oxidation step.

Benzo-furan derivative
