Asymmetric Construction of Quaternary Carbons from Chiral Malonates: Selective and Versatile Total Syntheses of the Enantiomers of α- and β-Cuparenones from a Common Optically Active Precursor

From a single chiron (R)-4, available with high enantiomeric purity (96percent) by simple enzymatic hydrolysis (PLE) of a prochiral malonate, were prepared convenient precursors of the two enantiomers of α- and β-cuparenones (1a,b and 2a,b).This versatile
