A novel strategy for catalytic asymmetric epoxidation of a wide variety of olefins by a porphyrin-inspired chiral manganese complex using H2O2 as a terminal oxidant in excellent yield with up to greater than 99% ee has been successfully developed.
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
