CBS Catalyst
Iyo CBS catalyst kana Corey-Bakshi-Shibata catalyst is asymmetric catalyst inotorwa kubva kuproline.Inowana kushandiswa kwakawanda mukuita kwehupenyu senge CBS kuderedza, Diels-Alder maitiro uye (3+2) cycloadditions.Proline, chiral compound inongoitika, inowanikwa zviri nyore uye zvakachipa.Inotamisa stereocenter yayo kune inokonzeresa iyo inozokwanisa kutyaira organic reaction yakasarudzika kune imwe yeaviri anogona enantiomers.Kusarudzika uku kunokonzerwa nekuomerwa kwe steric mumamiriro ekuchinja anokura kune imwe enantiomer asi kwete kune imwe.

CBS Catalysts yeAsymmetric Reduction uye Asymmetric Synthesis
Iyo CBS (Corey-Bakshi-Shibata) oxazaborolidine catalyst yakashandiswa mukuderedza asymmetric yeprochiral ketones.Zvimwe zvinoshandiswa zvinosanganisira enantioselective synthesis ye-α-hydroxy acids, α-amino acids, C2-symmetrical ferrocenyl diols, uye propargyl alcohols.

(R)-(+)-2-Methyl-CBS-oxazaborolidine (ca. 1mol / L muToluene) CAS: 112022-83-0 inogona kushandiswa sechinhu chinokonzera mu asymmetric borane kuderedza perfluoroalkyl ketones.Zvimwe zvinoshandiswa zvinosanganisira enantioselective synthesis ye-α-hydroxy acids, α-amino acids, C2 symmetrical ferrocenyl diols, uye propargyl alcohols.Inoshandiswawo mukuderedza desymmetrizing inotungamirira ku (S) -4-hydroxycyclohexenone.Inobatsira mukugadzira stereospecific motifs senge α-hydroxy acids, α-amino acids, symmetrical ferrocenyl diols uye propargyl alcohols.

(R)-(+)-2-Methyl-CBS-oxazaborolidine (ca. 1mol / L muToluene) CAS: 112022-83-0 inonzi organoboron catalyst inoshandiswa mukugadzirwa kwehupenyu.Iyi catalyst, yakagadzirwa naItsuno naElias James Corey, inogadzirwa nekupisa (R) - (+) -2- (diphenylhydroxymethyl) pyrrolidine pamwe ne trimethylboroxine kana methylboronic acid.Icho chishandiso chakanakisa chekubatanidza madoro mune yakakwira enantiomeric ratio.Kazhinji, 2-10 mol% yeiyi catalyst inoshandiswa pamwe chete neborane-tetrahydrofuran (THF), borane-dimethylsulfide, borane-N, N-diethylaniline, kana diborane seyoborane sosi.Enantioselective kuderedza kushandisa chiral oxazaborolidine catalysts yakashandiswa mukugadzirwa kwemishonga yekutengeserana yakadai se ezetimibe uye aprepitant.
