An efficient synthesis of chiral 3-arylindanones via iridium-catalyzed asymmetrichydrogenation of 3-arylindenones has been developed. The reaction showed good compatibility with various functional groups, delivering a variety of 3-arylindanones in excellent yields and with good enantioselectivities. The reaction was also carried out on a gram-scale, delivering the product in quantitative yield. In

Efficient kinetic resolution (KR) occurs in asymmetric transfer hydrogenation (ATH) reactions of racemic 3-aryl-1-indanones using commercial (R,R)- or (S,S)-Ts-DENEB as a catalyst, a 1 : 5 mixture of HCO2H and Et3N as a hydrogen source and MeOH as solvent. This process at room temperature produces near equal yields of cis-3-arylindanols with high dr and ee, and unreacted 3-arylindanones with excellent
高效动力学拆分 (KR) 发生在外消旋 3-aryl-1-indanones 的不对称转移氢化 (ATH) 反应中,使用商业 ( R , R )-或 ( S , S )-Ts-DENEB 作为催化剂,a 1:5 HCO 2 H和Et 3 N的混合物作为氢源和MeOH作为溶剂。这个过程在室温下产生几乎相等的顺式-3-芳基二氢萘并具有高 dr 和 ee 的产率,以及具有优异 ee 的未反应的 3-芳基二氢萘酮。使用 ATH-KR 方案生成的 3-芳基茚满醇和 3-芳基茚满酮的立体选择性转化形成 (+)-吲达曲林并具有合成价值 ( R)-6-甲基-4-苯基香豆素,是制备( R )-托特罗定、( S )-4-aryl-3,4-dihydroquinoline-2( 1H )-one和( S )的关键中间体-4-aryl-3,4-dihydroisoquinoline-1(2 H )-one。

A recoverable dendrimeric supported prolinol was used as a catalyst in the asymmetric reduction of indanones and tetralones to give separable cis and trans isomers up to 97% ee. This method was also applied in the enantio selective synthesis of the antidepressant drug (+)-sertraline. (c) 2006 Elsevier Ltd. All rights reserved.
