2-溴-4,5-二甲氧基苯甲酸 | 2-bromo-4,5-dimethoxybenzoic acid | 6286-46-0 | C9H9BrO4 | 261.072 |
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%.
