I-Shanghai Ruifu Chemical Co., Ltd. ngumenzi ohamba phambili kunye nomthengisi we-(S)-(-)-1,1'-Bi-2-naphthol (CAS: 18531-99-2) enomgangatho ophezulu, yeyemveliso yamayeza. phakathi kwaye ingasetyenziselwa ukuhlanganiswa kwe-chiral intermediates kunye neziyobisi ze-chiral.

I-Shanghai Ruifu Chemical Co., Ltd. idlala indima ebalulekileyo kwi-chemistry ye-chiral, inkampani izinikele ekuveliseni i-chiral compounds.Iimveliso zethu zinconywa ngokubanzi ngabathengi.

(S)-(-)-1,1'-Bi-2-naphthol (CAS: 18531-99-2) i-organic compound ehlala isetyenziswa njenge-ligand ye-transition-metal catalysed asymmetric synthesis.I-BINOL ine-axial chirality kwaye ii-enantiomers ezimbini zinokwahlulwa ngokulula kwaye zizinzile ngokubhekiselele kugqatso.Ukujikeleza okuthe ngqo kwee-enantiomers ezimbini yi-±35.5 ° (C=1 kwi-THF).I-BINOL isandulela kwenye i-chiral ligand ebizwa ngokuba yi-BINAP.(S) -BINOL inokulungiswa ngokuthe ngqo kwi-asymmetric oxidative coupling ye-2-naphthol nge-copper (II) chloride.I-chiral ligand kule reaction yi (S)-(+)-amphetamine.(S)-(-)-1,1'-Bi-2-naphthol (CAS: 18531-99-2) isetyenziswe kwi-stereoelective synthesis yePeloruside A. Kwakhona isetyenziswe kwi-synthesis ye-BINAP-based aminophosphines kwaye isetyenziselwa ukuhlanganiswa kwee-reagents ezahlukeneyo ze-chiral.
