Oxidation of macrocyclicphosphine oxide-dithioether 1 produces only the dl form of disulfoxide 2. This selectivity can be rationalized by comparing the crystal structures of starting material and product, and on the basis of VT NMR data, which suggest that the starting macrocycle is conformationally constrained in solution.
