The regioselecttve 4-benzylation of 2,4-dihydroxybenzaldehyde
Mendelson, Wilford L.,Holmes, Monica,Dougherty, Jack
, p. 593 - 601 (1996)
A regioselective mono-benzylation of the 4-hydroxyl group of 2,4-dihydroxybenzaldehyde (2) to produce 1 under extremely mild basic conditions (NaHCO3 or KF) has been developed. This approach gives improved regioselectivity relative to earlier methods.
