The two enantiomers of this compound are used in organic chemistry as chiral auxiliaries. ==Preparation== The enantioselective synthesis was accomplished by J. K. Whitesell by adding Pseudomonas fluorescens lipase to racemic ''trans''-2-phenylcyclohexyl chloroacetate. This enzyme is able to hydrolyze the ester bond of the (-) enantiomer but not the (+) enantiomer. The (−)-cyclohexanol and the (+)-ester are separated by fractional crystallization and the isolated (+)-ester hydrolyzed to the (+)-cyclohexanol in a separate step. The enantiomers have also been prepared by the Sharpless asymmetric dihydroxylation of 1-phenylcyclohexene to the diol followed by the selective reduction of the 1-hydroxyl group by Raney nickel. 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「Trans-2-Phenyl-1-cyclohexanol」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.
