摘要：

"Chemical Equation Presented" α-Substitution is fine: α-Alkoxycarbonyl and α-aminocarbonyl compounds are good substrates for the recently developed tosylhydrazide-promoted Pd-catalyzed cross-coupling of carbonyls with aryl halides. The reac-tion gives rise to enol ethers and enamines, respectively, which are useful synthetic intermediates in heterocyclic synthesis. Otherwise, they can be hydrolyzed to give α,α- disubstituted aldehydes. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
