Codsiga:

Shanghai Ruifu Chemical Co., Ltd. waa saaraha iyo soo saaraha ugu horreeya ee (R)-(+) -1,1'-Bi-2-naphthol (CAS: 18531-94-7) oo leh tayo sare leh, oo si ballaaran loo isticmaalo organic isku-dubarid, isku-dubarid dhexdhexaadiyeyaasha dawooyinka iyo isku-dhafka kiimikada ee wanaagsan.

Shanghai Ruifu Chemical Co., Ltd. waxay door muhiim ah ka ciyaartaa kimistariga chiral, shirkadu waxay ka go'an tahay soo saarista xeryahooda chiral.Alaabadayada waxaa si weyn u ammaanay macaamiisha.

(R)-(+)-1,1'-Bi-2-naphthol (CAS: 18531-94-7) waxaa lagu helaa xalinta midabka BINOL, kaas oo inta badan laga sameeyo 2-naphthol oo ay ka sameysan tahay birta(III) chloride iyada oo loo marayo falcelin xagjir ah.(R)-(+)-1,1'-Bi-2-naphthol si weyn ayaa loogu isticmaalay codsiyo kala duwan: 1) wakiilada kicinta chiral ee kicinta, falcelinta asymmetric sida falcelinta Diels-Alder, falcelinta ene, ama sida Lewisacids ;2) hoos u dhigista ketones-ka;3) Isku-dubaridka macrocycles iyo xeryahooda kale ee xiisaha leh.Chiral binapthol imminium cusbo horudhac ah oo loo isticmaalo oksaydhka asymmetric katalytic ee sulfides ilaa sulfoxides.Chiral lanthanide triflates oo laga sameeyay binaphthol waxay u adeegaan sidii kicinta falcelinta Diels-Alder.Soosaarayaasha binaphthol ayaa dhawaan loo adeegsaday dib u habeynta Claisen asymmetric iyo epioxidations asymmetrical.Kala soocida lithium aluminium hydride ee diols-yadan (BINAP-H) ayaa si weyn loogu isticmaalay dhimista ketones.Waxaa loo isticmaalaa diyaarinta biosynthetic for oksaydhka enantioselective ee naphthols ilaa binaphthyldiol leh horseradish peroxidase kicinta.
