Taupānga:

Ko Shanghai Ruifu Chemical Co., Ltd. te kaihanga matua me te kaiwhakarato o (S)-(-)-1,1'-Bi-2-naphthol (CAS: 18531-99-2) me te kounga teitei, no te rongoa takawaenga ka taea te whakamahi mo te whakahiato o nga kaiwawao chiral me nga raau taero chiral.

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.

Ko te (S)-(-)-1,1'-Bi-2-naphthol (CAS: 18531-99-2) he pūhui waro e whakamahia ana hei herenga mo te whakahiato hangarite whakawhiti-whakarewa.Ko te BINOL he axial chirality a ka taea te wehe i nga enantiomers e rua, ka mau tonu ki te whakaheke.Ko te hurihanga motuhake o nga enantiomers e rua ko ± 35.5° (C=1 i te THF).Ko te BINOL he tohu mo tetahi atu ligand chiral e kiia nei ko BINAP.(S)-BINOL Ka taea te whakarite tika mai i te hononga oxidative hangarite o te 2-naphthol me te parahi(II) pūhaumāota.Ko te ligand chiral i roto i tenei tauhohenga ko (S)-(+)-amphetamine.(S)-(-)-1,1'-Bi-2-naphthol (CAS: 18531-99-2) e whakamahia ana i roto i te stereoselective synthesis o Peloruside A. I whakamahia ano hoki i roto i te whakahiato o nga aminophosphines i runga i te BINAP ka whakamahia mo te whakahiato o nga momo reagents chiral.
