S. Combes et Jp. Finet, A SIMPLE SYNTHESIS OF THE NATURAL 2,5-DIALKYLRESORCINOL FREE-RADICAL SCAVENGER ANTIOXIDANT - RESORSTATIN, Synthetic communications, 27(21), 1997, pp. 3769-3778
3,5-Dimethoxybenzoic acid 3 has been transformed into olivetol dimethy
l ether 6 in three steps in 79% yield. Directed ortho-metallation-alky
lation of 6, followed by boron tribromide demethylation resulted in a
simple and inexpensive synthesis of resorstatin, in 70% overall yield
from 3.
