The successful one step synthesis did not require protecting groups and provided high yields. The obtainment of 1-(4′-hydroxybenzyl)-6,7-dihydroxyisochroman (1) indicates that this protocol can be used to synthesize oxygenated analogues of benzyl-tetrahydroisoquinoline alkaloids, such as demethyl-coclaurine (2). This methodology could provide a general procedure for the synthesis of hydroxyisochromans
