Asymmetric Allylic Alkylation of Ketone Enolates: An Asymmetric Claisen Surrogate. Erin C. Burger and Jon A. Tunge* Department of Chemistry, University of Kansas, Lawrence, KS 0 Supporting Information Experimental Materials. Benzene was dried over sodium metal. All other materials were used as received. β-ketoesters a-h were prepared by the addition of diketene to the corresponding allylic alcohols. β-ketoester f was prepared by the DMAP catalyzed condensation of β-ketoethylester and allylic alcohol. β-ketoesters i-l were prepared by the condensation of the corresponding acid chloride with Meldrum s acid followed by addition of the appropriate allylic alcohol. H NMR spectra were obtained on a Bruker Avance 00 or a Bruker Avance 00 DRX spectrometer and referenced to residual protio solvent signals. Structural assignments are based on H, C, DEPT-, COSY, and HMQC spectroscopies. General procedure for catalytic rearrangements: In a Schlenk tube under Ar, allylβ-ketoester (. mmol) and either Pd(PPh ) (0 mol %) or the combination of Pd (dba) ( mol %) and Trost ligand (0 mol %) were dissolved in ml of benzene. The reaction was allowed to stir under Ar for the reported time. Following solvent evaporation the crude product was purified via flash chromatography (SiO, 0% Et O: Hex).
