reported here the low loading porphyrin-inspired high-valent manganese (IV)-oxo complex was applied in oxidative kineticresolution (OKR) of racemic heterocyclic sulfoxides using the environmentally benign hydrogen peroxide for the first time. This approach allows for rapid OKR (0.5 h) of a variety of racemic sulfoxides (including pyridine, pyrimidine, pyrazine, thiazole, benzothiazole, thiophene) in

A novel one-pot protocol for the C4-selective sulfonylation of pyridines is described. Contrary to previous methods positional selectivity is controlled by a tailored combination of base and solvent.
