Asymmetric Synthesis of 1-Tetralones Bearing a Remote Quaternary Stereocenter through Rh-Catalyzed C–C Activation of Cyclopentanones

Abstract
Herein, we describe the preparation of 1-tetralones bearing a remote quaternary stereocenter in a highly enantioselective manner. A sequence of Pd-catalyzed asymmetric 1,4-addition and Rh-catalyzed enantiospecific C−C/C−H activation delivers diverse 1-tetralones with a C4 quaternary stereocenter, which are prepared in good overall yields and high enantioselectivity.
