CBS Catalyst
Catalysta CBS seu Corey-Bakshi-Shibata catalyst catalysta asymmetrica est e proline derivata.Multos usus invenit in reactionibus organicis sicut reductiones CBS, reactiones Diels-Alder et (3+2) cycloadditiones.Proline, compositio chiralis naturaliter occurrens, prompte et viliter praesto est.Stereocenter suum ad catalysmum transfert, qui rursus organicam reactionem selectivam ad unum e duobus possibilibus enantiomers agere potest.Haec selectivity ob stericas contentiones in statu transeunte, qui pro uno enantiomer sed non pro altero enucleatur.
CBS catalysts de reductione asymmetrica et synthesi asymmetrica
CBS (Corey-Bakshi-Shibata) catalysta oxazaborolidine adhibita est in reductione asymmetrica ketonum prochiralorum.Aliae applicationes includunt synthesim enantioselectivam ab acida hydroxy, amino acida, ferrocenyl diols C2-symmetricam, et alcoholum propargyl.
(R)-(+)-2-Methyl-CBS-oxazaborolidines (ca. 1mol/L in Toluene) CAS: 112022-83-0 adhiberi potest ut catalysta in asymmetrica borana reductione perfluoroalkyl ketonum.Aliae applicationes includunt synthesim enantioselectivam ab acidis hydroxyis, acidis α-amino, C2 symmetriis ferrocenyl diolis, et alcoholis propargyl.Adhibetur etiam in reductione desymmetrica ad (S) -4-hydroxycyclohexenone.Utile est in motionibus stereo- riis productionibus, ut ab acida hydroxy, amino acida, ferrocenyl diols symmetriis et alcohols propargyl.
(R)-(+)-2-Methyl-CBS-oxazaborolidines (ca. 1mol/L in Toluene) CAS: 112022-83-0 organoboron catalyst quod in synthesi organica adhibetur.Haec catalysta, ab Itsuno et Elia James Corey evoluta, generatur ex calefactione (R)-(+)-2-(diphenylhydroxymethyl) pyrrolidine una cum acido trimethylboroxino vel methylboronico.Egregium instrumentum est ad synthesim alcoholis in ratione enantiomeric alta.Fere 2-10 mol% huius catalysti adhibetur una cum borano-tetrahydrofuran (THF), borane-dimethylsulfide, borane-N, N-diethylanilino, vel diborane ut borane.Reductio enantioselectiva utens oxazaborolidine catalystarum chiralium adhibita est in synthesi medicamentorum mercatorum sicut ezetimibe et aprepitant.
