Taupānga:

Ko Shanghai Ruifu Chemical Co., Ltd. te kaihanga matua me te kaiwhakarato o (R)-(+)-1,1'-Bi-2-naphthol (CAS: 18531-94-7) me te kounga teitei, e whakamahia nuitia ana i roto i te waro. te whakahiato, te whakahiatotanga o nga takawaenga rongoa me te whakahiato matū pai.

He mahi nui a Shanghai Ruifu Chemical Co., Ltd. i roto i te matū chiral, e u ana te kamupene ki te hanga i nga pūhui chiral.Ko a maatau hua e whakanuia ana e nga kaihoko.

(R)-(+)-1,1'-Bi-2-naphthol (CAS: 18531-94-7) ka riro mai i te taumira o te BINOL racemic, he mea hanga mai i te 2-naphthol i whakahiatotia e te rino(III) chloride. na roto i te tauhohenga tuwhena.(R)-(+)-1,1'-Bi-2-naphthol kua whakamahia whānuitia mo nga momo tono: 1) nga kai whakakorikori chiral mo te catalytic, tauhohe hangarite penei i te Diels-Alder tauhohenga,ene tauhohenga, hei Lewisacids ranei. ;2) whakaiti enantioselective o ketones;3) te whakahiatotanga o te huringa macro chiral me etahi atu puhui whakamere.He chiral binapthol imminium salt precursor i whakamahia i roto i te catalytic whakahiato hārite o te sulfide ki sulfoxides.Ko nga triflates chiral lanthanide i hangaia mai i te binaphthol hei whakakorikori mo nga tauhohenga asymmetric Diels-Alder.Ko nga hua o te binaphthol katahi ano ka whakamahia i roto i nga whakarereketanga a Claisen hangarite me nga whakapooratanga hangarite.Ko te lithium aluminum hydride derivative o enei diols (BINAP-H) kua whakamahia nui mo te whakaheke i nga ketones.Ka whakamahia i roto i te whakarite biosynthetic mo te oxidation enantioselective o naphthols ki te binaphthyldiols me te horseradish peroxidase catalyst.
