Aldol condensations on alpha-,beta-epoxyaldehyde having a remote alkoxy group have been realized. A rationalization of the outcome of this condensation is discussed, relying on the dominant conformers revealed by molecular modeling of anti and sny gamma,delta-epoxy beta-hydroxyesters and their NMR and IR spectrostroscopic properties.
