Abstract The synthesis of a highly functionalized phenolic diaryl ether 5, 5′-oxybis (4- hydroxy-3-methoxybenzaldehyde)(1) potentially interesting as a new scaffold for drug design, has been carried out using Ullmann coupling conditions. An unusual benzyl migration in o-benzyloxyphenol moiety occurred during this reaction leading to an unexpected compound identified as 4-(benzyloxy)-3-(2-(benzyloxy)-4-formyl-6- ...
