The invention relates to novel, scalable synthetic routes that allow for direct reduction of enones to the corresponding saturated alcohols. The invention relates, in certain aspects, to synthetic routes that allow for the reduction of enones to the corresponding ketones. Such reactions take place under mild conditions, are compatible with a wide range of functional groups, and expand the repertoire of existing green chemistry methodology. In certain embodiments, the reactions are run in aqueous solvent.

aldol condensation from various ketones and a wide range of aldehydes was catalyzed by l-proline–TEA (triethylamine) in MeOH at room temperature, affording the corresponding (E)-α,β-unsaturated ketones in excellent yields. By using the method, some complicated (E)-α,β-unsaturated ketone C-glycosides were obtained from unmodified ketone C-glycosides and aldehydes. This reaction proceeds through a new
