Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-addition of an aromatic nucleophile to an α,β-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 α,β-unsaturated aldehyde.
非金属手性有机催化剂用于催化芳香族亲核试剂对α,β-不饱和醛的1,4-加成反应。芳香族亲核试剂可以是N,N-二取代苯胺化合物或其类似物。该反应高效、对映选择性好,并且适用于多种取代和未取代的芳香族亲核试剂和醛。本发明还提供了一种方法,用于去氨基芳香族N,N-二取代胺,例如由芳香族亲核试剂对α,β-不饱和醛的1,4-加成反应所产生的化合物。
