Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-addition of an aromatic nucleophile to an &agr;,&bgr;-unsaturated aldehyde. The aromatic nucleophile may be an N,N-disubstituted aniline compound, or an analog thereof. The reaction is efficient and enantioselective, and proceeds with a variety of substituted and unsubstituted aromatic nucleophiles and aldehydes. The invention also provides a method for the deamination of aromatic N,N-disubstituted amines such as those resulting from the 1,4-addition of an aromatic nucleophile to an &agr;,&bgr;-unsaturated aldehyde.
非金属手性有机催化剂被用于催化芳香核亲电体对α,β-不饱和醛的1,4-加成反应。芳香核亲电体可以是N,N-二取代苯胺化合物,或其类似物。该反应高效、选择性,可用于各种取代和未取代的芳香核亲电体和醛。该发明还提供了一种去氨化芳香N,N-二取代胺类化合物的方法,例如由芳香核亲电体对α,β-不饱和醛的1,4-加成反应产生的化合物。
