Webα,β-Unsaturated carbonyl compounds are organic compounds with the general structure (O=CR)−C α =C β-R.Such compounds include enones and enals.In these compounds the carbonyl group is conjugated with an alkene (hence the adjective unsaturated).Unlike the case for carbonyls without a flanking alkene group, α,β-unsaturated carbonyl compounds … Web[‌133‌,‌134‌] Catalytic amounts of chiral boron reducing agents are much more successful for the syntheses of enantioenriched allylic alcohols from enones, and the proline-derived …
