Determination of the absolute configuration of the enantiomers of dihydroquinolines, isolated by chiral chromatography, by non empirical analysis of circular dichroism spectra and X-ray analysis

Recent Highlights in Ketenimine Chemistry

“…[61] In compound 123 (Scheme 41), the exchange of the benzene ring connecting the acetal and ketenimine functions for a heterocyclic ring had pronounced consequences for the magnitudes of the energy barriers of the two mechanistic steps of the tandem cyclizations experienced by acetalic ketenimines.
