Highly regioselective one-pot synthesis of 7-hydroxy-6-methylphthalide from 3-hydroxy-4-methylbenzylalcohol
Duan, Meili,Toney, Michael D.
, p. 2869 - 2874 (2005)
7-Hydroxy-6-methylphthalide 2 was synthesized with high regioselectivity and moderate yield using a novel one-pot synthesis that employed 3-hydroxy-4-methylbenzylalcohol 1 and formaldehyde in the presence of tin(IV) chloride as catalyst and triethylamine
