Shanghai Ruifu Chemical Co., Ltd. yog cov chaw tsim khoom thiab chaw muag khoom ntawm (R)-(+)-1,1'-Bi-2-naphthol (CAS: 18531-94-7) nrog cov khoom zoo, dav siv hauv cov organic. synthesis, synthesis ntawm pharmaceutical intermediates thiab nplua tshuaj synthesis.

Shanghai Ruifu Chemical Co., Ltd. plays lub luag haujlwm tseem ceeb hauv chiral chemistry, lub tuam txhab tau cog lus rau kev tsim cov chiral compounds.Peb cov khoom tau qhuas los ntawm cov neeg siv khoom.

(R)-(+)-1,1'-Bi-2-naphthol (CAS: 18531-94-7) yog tau los ntawm kev daws teeb meem ntawm racemic BINOL, uas feem ntau yog ua los ntawm 2-naphthol catalyzed los ntawm hlau (III) chloride los ntawm cov tshuaj tiv thaiv radical.(R)-(+)-1,1'-Bi-2-naphthol tau dav siv rau ntau yam kev siv: 1) chiral inducing cov neeg ua haujlwm rau catalytic, asymmetric cov tshuaj tiv thaiv xws li Diels-Alder cov tshuaj tiv thaiv, ene cov tshuaj tiv thaiv, los yog Lewisacids ;2) enantioselective txo qis ntawm ketones;3) synthesis ntawm chiral macrocycles thiab lwm yam kev sib xyaw ua ke.Ib tug chiral binapthol imminium ntsev precursor siv nyob rau hauv catalytic asymmetric oxidation ntawm sulfides rau sulfoxides.Chiral lanthanide triflates tsim los ntawm binaphthol ua cov catalysts rau asymmetric Diels-Alder cov tshuaj tiv thaiv.Derivatives ntawm binaphthol tsis ntev los no tau siv nyob rau hauv asymmetric Claisen rearrangements thiab asymmetric epoxidations.Cov lithium aluminium hydride derivative ntawm cov diols (BINAP-H) tau siv dav rau kev txo cov ketones.Nws yog siv rau hauv biosynthetic npaj rau enantioselective oxidation ntawm naphthols rau binaphthyldiols nrog horseradish peroxidase catalyst.
