diastereomeric resonances in their NMR spectra. Product ratios from alkylation by acetoacetate were thermodynamic, while those from alkylation by the enamine were presumed to be kinetic. The excess of one diastereomer over the other, relating in principle to an “optical yield” at the new chiral carbon center induced by the existing metal chirality, ranged from 10 to 64% depending on the nucleophile and the electrophile
