Abstract: The title compound, C₂₁H₂₃ClN₂O₇S₂, is a representative of moderately active hydroxyacid synthase inhibitors. The structure has a sulfonylimine bond [-N=C(-SMe)-CH] and not sulfonylamino [-NH-C(-SMe)=C], contrary to expectations. There is a strong intramolecular hydrogen bond between the imine H and the acid carbonyl group, and a weaker one between the imine carbonyl group and a benzene H atom.
