I-Shanghai Ruifu Chemical Co., Ltd. ngumenzi ohamba phambili kunye nomthengisi we (R)-(+)-1,1'-Bi-2-naphthol (CAS: 18531-94-7) kunye nomgangatho ophezulu, osetyenziswa ngokubanzi kwizinto eziphilayo. i-synthesis, i-synthesis ye-pharmaceutical intermediates kunye ne-fine chemical synthesis.

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

(R)-(+)-1,1'-Bi-2-naphthol (CAS: 18531-94-7) ifunyenwe ngesisombululo se-racemic BINOL, edla ngokwenziwa kwi-2-naphthol catalyzed ngentsimbi (III) chloride. ngokusabela okukhulu.(R) - (+) -1,1'-Bi-2-naphthol isetyenziswe ngokubanzi kwizicelo ezahlukeneyo: 1) i-chiral inducing agents for catalytic, reactions asymmetric ezifana ne-Diels-Alder reaction, i-ene reaction, okanye njenge-Lewisacids. ;2) ukunciphisa i-enantioselective yeetoni;3) ukuhlanganiswa kwe-chiral macrocycles kunye nezinye iikhompawundi ezinomdla.I-chiral binapthol i-imminium precursor yetyuwa esetyenziswa kwi-catalytic asymmetric oxidation yeesulfides ukuya kwi-sulfoxides.I-Chiral lanthanide triflates eyenziwe kwi-binaphthol isebenza njenge-catalysts ye-asymmetric reactions Diels-Alder.I-derivatives ye-binaphthol isandula kusetyenziswa kwi-asymmetric Claisen rearrangements kunye ne-asymmetric epoxidations.I-lithium aluminium hydride derivative of these diols (BINAP-H) isetyenziswe ngokubanzi ekunciphiseni i-ketones.Isetyenziselwa ukulungiswa kwe-biosynthetic ye-enantioselective oxidation ye-naphthols ukuya kwi-binaphthyldiols kunye ne-horseradish peroxidase catalyst.
