Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-hydride reduction of an α,β-unsaturated carbonyl compound. The α,β-unsaturated carbonyl compound may be an aldehyde or cyclic ketone, and the hydride donor may be a dihydropyridine. The reaction is enantioselective, and proceeds with a variety of hydride donors, catalysts, and substrates. The invention also provides compositions effective in carrying out the 1,4-hydride addition of α,β-unsaturated carbonyl compounds.
非金属手性有机催化剂被用于催化α,β-不饱和羰基化合物的1,4-氢化还原反应。α,β-不饱和羰基化合物可以是醛或环状酮,氢化供体可以是二氢吡啶。该反应是对映选择性的,并且可以使用多种氢化供体、催化剂和底物进行。本发明还提供了在进行α,β-不饱和羰基化合物的1,4-氢化加成反应时有效的组合物。
