Arylation of α‐Chiral Ketones by Palladium‐Catalyzed Cross‐Coupling Reactions of Tosylhydrazones with Aryl Halides

Papa was a rollin' ketone: Arylation of ketones with preservation of the chirality in configurationally unstable α-chiral ketones has been achieved by the palladium-catalyzed cross-coupling reaction between tosylhydrazones and aryl halides (see scheme; Boc=tert-butoxycarbonyl, Ts=4-toluenesulfonyl). The regioselectivity in the β-hydride elimination step is key for the retention of configuration. Detailed facts of importance to specialist readers are published as "Supporting Information".
