α,β-不饱和醛是一类具有生物化学活性的化合物,有浓郁的肉香和果香香味,广泛地存在于自然界的水果、蔬菜、禽肉和畜肉之中。我们知道,α,β-不饱和醛是有机合成中重要的原料和中间体。它与共轭二烯发生DielsAlder反应可合成一系列脂环族烯烃化合物;在碱催化剂存在下,它又能与负碳离子进行亲核加成的Michael反应;此外,它与酰胺、硫化氢、醇、硫醇等化合物进行加成反应,生成 Alpha, beta-unsaturated aldehydes are a group of biochemically active compounds that are rich in meaty and fruity aromas and are found extensively in fruits, vegetables, poultry, and livestock meat in nature. We know that α, β-unsaturated aldehydes are important raw materials and intermediates in organic synthesis. DielsAlder reaction with conjugated dienes can synthesize a series of alicyclic alkene compounds. In the presence of base catalysts, Michael reactions with nucleophilic additions of carbanions to amides of carbon atoms. In addition, it can react with amides, hydrogen sulfide, alcohols , Thiols and other compounds for addition reaction
