Wang, Pengyang published the artcileNovel Axially Chiral Ligand-Enabled Copper-Catalyzed Asymmetric Oxidative Coupling of 2-Naphthols for the Synthesis of 6,6′-Disubstituted BINOLs, Quality Control of 2960-93-2, the publication is Organic Letters (2022), 24(12), 2321-2326, database is CAplus and MEDLINE.
Novel axially chiral ligands such as I [R = H, 1-naphthyl, 9-anthryl, etc.] were designed and synthesized by merging the chelating picolinic acid with substituted BINOLs. The in-situ-prepared copper catalysts from the ligands and CuI enable the asym. oxidative coupling of 2-naphthols, affording 6,6′-disubstituted BINOLs such as II [R1 = H, i-Pr, Ph, etc.] in up to 89% yield with good enantioselectivities (up to 96:4 e.r.).
Organic Letters published new progress about 2960-93-2. 2960-93-2 belongs to naphthyridine, auxiliary class Naphthalene,Ether,Other MOF ligands,Organic ligands for MOF materials, name is 2,2′-Dimethoxy-1,1′-binaphthalene, and the molecular formula is C9H8O4, Quality Control of 2960-93-2.
