CBS Catalyst
O le CBS catalyst po'o le Corey-Bakshi-Shibata catalyst o se fa'aupuga asymmetric e maua mai le proline.E maua ai le tele o fa'aoga i gaioiga fa'aola e pei o le fa'aitiitiga o le CBS, Diels-Alder reactions ma (3+2) cycloadditions.O le Proline, o se fa'aputu fa'anatura, e faigofie ma taugofie.Na te fa'aliliuina lona nofoaga autu i le catalyst lea e mafai ai ona fa'aosoina se tali fa'aletino filifilia i se tasi o enantiomers e lua.O lenei filifiliga e mafua ona o le faʻalavelave faʻafuaseʻi i le tulaga o suiga e atiaʻe mo le tasi enantiomer ae le o le isi.

CBS Catalysts mo Asymmetric Reduction ma Asymmetric Synthesis
O le CBS (Corey-Bakshi-Shibata) oxazaborolidine catalyst ua faʻaaogaina i le faʻaitiitiga asymmetric o prochiral ketones.O isi talosaga e aofia ai le enantioselective synthesis o α-hydroxy acids, α-amino acids, C2-symmetrical ferrocenyl diols, ma propargyl alcohols.

(R)-(+)-2-Methyl-CBS-oxazaborolidine (ca. 1mol / L i Toluene) CAS: 112022-83-0 e mafai ona faʻaaogaina e fai ma faʻamalosi i le faʻaitiitia o le borane asymmetric o ketones perfluoroalkyl.O isi talosaga e aofia ai le enantioselective synthesis o α-hydroxy acids, α-amino acids, C2 symmetrical ferrocenyl diols, ma propargyl alcohols.E faʻaaogaina foʻi i se faʻaitiitiga desymmetrizing e tau atu i (S) -4-hydroxycyclohexenone.E aoga i le gaosiga o mea faʻapitoa e pei ole α-hydroxy acids, α-amino acids, symmetrical ferrocenyl diols ma propargyl alcohols.

(R)-(+)-2-Methyl-CBS-oxazaborolidine (ca. 1mol/L i le Toluene) CAS: 112022-83-0 o se faʻapipiʻi organoboron lea e faʻaaogaina i le faʻaogaina o meaola.O lenei faʻamalosi, na atiaʻe e Itsuno ma Elias James Corey, e gaosia e ala i le faʻamafanafanaina (R) - (+) -2-(diphenylhydroxymethyl) pyrrolidine faʻatasi ai ma le trimethylboroxine poʻo le methylboronic acid.O se meafaigaluega sili ona lelei mo le tuʻufaʻatasia o ava malosi i le maualuga enantiomeric ratio.E masani lava, 2-10 mol% o lenei catalyst e faʻaaogaina faʻatasi ma le borane-tetrahydrofuran (THF), borane-dimethylsulfide, borane-N, N-diethylaniline, poʻo le diborane e fai ma puna borane.Enantioselective reduction faʻaaogaina chiral oxazaborolidine catalysts ua faʻaaogaina i le tuʻufaʻatasia o fualaau faʻatau pisinisi e pei o le ezetimibe ma le aprepitant.
