An enantioselective synthesis of (3S,3aS,7aR)-wine lactone, a major aroma component of white wine and citrus juices, was achieved starting from (S)-2-methyl-3-butenoic acid. An intramolecular Diels-Alder reaction was employed as a key step.
(3S,3aS,7aR)-葡萄酒内酯是白葡萄酒和柑橘汁的主要香气成分,从 (S)-2-methyl-3-butenoic 酸开始实现了对映选择性合成。分子内 Diels-Alder 反应被用作关键步骤。
