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

Optically active sulfoxides are compounds of high interest in organic chemistry. Herein, we report the preparation of a set of chiral heteroaryl alkyl, cyclohexyl alkyl, and alkyl alkyl sulfoxides by using enantioselective sulfoxidation reactions employing three Baeyer-Villigermonooxygenases (BVMOs). Careful selection of the reaction conditions, starting sulfide, and biocatalyst can be used to achieve

Two new monooxygenase biocatalysts, the Baeyer–Villigermonooxygenase BVMO145 and the flavin monooxygenase FMO401 from Almac library, have been found to catalyse the enantiodivergent oxidation of sulfides bearing N-heterocyclic substituents into sulfoxides under mild and green conditions. The biocatalyst BVMO145 provides (S)-sulfoxides while the flavin monooxygenase FMO401 affords (R)-sulfoxides with
两种新的单加氧酶生物催化剂,Baeyer-Villiger 单加氧酶 BVMO145 和来自 Almac 库的黄素单加氧酶 FMO401,被发现可以在温和和绿色条件下催化带有 N-杂环取代基的硫化物对映异构氧化成亚砜。生物催化剂 BVMO145 提供 ( S )-亚砜,而黄素单加氧酶 FMO401 提供 ( R )-亚砜,具有良好的转化率和高 ee。

The structure determination of the title compound, [PdCl2(C6H15P)(C8H11 NOS)], revealed the occurrence of discrete molecules, in which the Pd atom has square-planar coordination geometry, with distances Pd-P 2.232 (1), Pd-N 2.128 (3) and Pd-Cl 2.293 (2) and 2.294 (2) Angstrom. The sulfoxide derivative acts as a monodentate ligand.
