Shao, You-Dong published the artcileOrganocatalytic Atroposelective Friedlander Quinoline Heteroannulation, SDS of cas: 452-63-1, the main research area is arylquinoline preparation organocatalyst atroposelective Friedlaender heteroannulation.
An atroposelective Friedlaender heteroannulation reaction of 2-aminoaryl ketones with α-methylene carbonyl derivatives was developed for the first time with chiral phosphoric acid as an efficient organocatalyst. The desired enantioenriched axially chiral polysubstituted 4-arylquinoline architectures were prepared with good to high yields and enantioselectivities (up to 94% yield and up to 97% ee). Furthermore, the products can be readily derivatized to afford an array of new quinoline-containing heteroatropisomers, which hold great potential in asym. catalysis and drug discovery.
Organic Letters published new progress about Enantioselective synthesis. 452-63-1 belongs to class bromides-buliding-blocks, name is 1-Bromo-4-fluoro-2-methylbenzene, and the molecular formula is C7H6BrF, SDS of cas: 452-63-1.
