Abstract

In this paper, norathyriol has been synthesised from 2-bromo-4, 5-dimethoxybenzoic acid and 1, 3, 5-trimethoxybenzene by a three-step sequence of transformations involving a Friedel–Crafts acylation with cyclisation and demethylation. The procedure was facile and should be easily scaled-up. The overall yields reached approximately 70%.
