Li, Yuanfeng published the artcileAsymmetric Epoxidation of α,β-Unsaturated Ketones Catalyzed by Chiral Iron Complexes of (R,R)-3,4-Diaminopyrrolidine Derived N4-Ligands with Camphorsulfonyl Sidearms, Recommanded Product: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Asian Journal of Organic Chemistry (2020), 9(4), 616-621, database is CAplus.
Three (R,R)-3,4-diaminopyrrolidine-based chiral N4 ligands and corresponding iron complexes were synthesized. The complexes were applied to the asym. epoxidation of various α,β-unsaturated ketones with H2O2 as an oxidant and carboxylic acid as an auxiliary. Good to excellent enantioselectivity (up to 97%) was achieved in the case of 2,2-dimethylbutyric acid as an auxiliary.
Asian Journal of Organic Chemistry published new progress about 21286-54-4. 21286-54-4 belongs to chlorides-buliding-blocks, auxiliary class Chiral,Chloride,Sulfonyl chlorides,Aliphatic cyclic hydrocarbon,Ketone, name is ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, and the molecular formula is C10H15ClO3S, Recommanded Product: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride.
