The asymmetric oxidation of a sulfur-containing nine-membered heterocycle was achieved for the late-stage introduction of chirality to the substituents of π-electron systems. The oxidation of the sulfur atom considerably influenced the phase-transition behaviour and crystallinity of the resulting π-electron systems.
