5-cis-Bromo-2,2,6,6-tetramethyltetrahydropyran-3-carboxylic acid

Abstract: Enantiomers of the title compound, C₁₀H₁₇BrO₃, form hydrogen-bonded centrosymmetric dimers, where the carboxy H atom serves as donor and the C=O group of a neighbouring molecule acts as acceptor. The proximity of two axial methyl substituents causes distortions of the tetrahydropyran chair conformation, which are evident from the magnitude of the endocyclic bond angle at the O atom and the values of the endocyclic torsion angles.
