Determining the Solution State Orientation of a Ti Enolate via Stable Isotope Labeling, NMR Spectroscopy, and Modeling Studies

Our group has used Ti-promoted aldol additions with an oxazolidineselone as the chiral auxiliary with much success. In these reactions, the Se atom in the auxiliary both promotes stereospecific addition as well as reports on, through the use of 77Se NMR spectroscopy, the ratio of diastereomers produ...
