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

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.
