Conformational control in the SuperQuat chiral auxiliary 5,5-dimethyl-4-iso-propyloxazolidin-2-one induces the iso-propyl group to mimic a tert-butyl group
1H NMR nOe spectroscopic studies reveal that conformational control in the enolates of N-acyl-5,5-dimethyl-4-iso-propyloxazolidin-2-ones ensures that the stereodirecting effect of its 4-iso-propyl-5,5-dimethyl functional group affords superior levels of facial selectivity normally associated with en...
