Abstract

Crystallographic analysis of the bromo-β-lactones obtained by addition of bromine to aqueous solutions of disodium 2,3-dimethylmaleate and 2,3-dimethylfumarate reveals stereochemistries opposite to those originally assigned and suggests that the first-formed intermediate in each case is an α-lactone.
