The present invention is generally directed to the use of L-proline and certain derivatives thereof to catalyze the asymmetric self-condensation of α,β-unsaturated aldehydes to form homodimer and heterodimer cyclohexadienals. Reaction conditions are mild and yet amenable to a variety of different substrates yielding molecules with complex scaffolds from simple precursors. This approach allows for diversification and synthesis of this structural class of compounds in sufficient quantity, purity and enantioselectivity for, e.g., biological investigations and use as fluorescent probes, anti-cancer agents, anti-bacterial agents, and/or anti-fungal agents. The present invention is also generally directed to the cyclohexadienals produced.
本发明通常涉及利用L-脯氨酸及其某些衍生物催化α,β-不饱和醛进行不对称自缩合,形成同二聚体和杂二聚体环己二烯醛。反应条件温和,且适用于多种不同的底物,从简单的原料生成具有复杂支架的分子。这种方法允许以足够的数量、纯度和对映选择性多样化合成这类结构的化合物,例如用于生物学研究以及作为荧光探针、抗癌剂、抗菌剂和/或抗真菌剂。本发明还一般涉及所生产的环己二烯醛。
