This catalyst, developed by Itsuno and Elias James Corey, is generated by heating (''R'')-(+)-2-(diphenylhydroxymethyl) pyrrolidine along with trimethylboroxine or methylboronic acid. It is an excellent tool for the synthesis of alcohols in high enantiometric excess. Generally a 2-10 mole% of this catalyst is used along with borane-tetrahydrofuran (THF), borane-dimethylsulfide, borane-''N'',''N''-diethylaniline, or diborane as the borane source. Asymmetric reduction using chiral oxazaborolidine catalysts has been used in the synthesis of commercial drugs such as ezetimibe and aprepitant. ==See also== * CBS catalyst * Corey-Itsuno reduction 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「(R)-2-Methyl-CBS-oxazaborolidine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
