  Synthesis of γ- and δ-Lactone Natural Products by Employing a trans–cis Isomerization/Lactonization Strategy

  摘要：

  4-羟基或/和5-羟基-(2E)-烯酸盐的碱性水解后进行酸处理，得到了相应的(2E)-烯酸，然后未经过进一步纯化直接进行内酯形成反应。粗酸与2,4,6-三氯苯甲酰氯在吡啶中反应，分别生成γ-内酯或δ-内酯，并伴随有反-顺异构化。通过这种方法合成了(±)-(4,5)-反-5-苄氧基-2-己烯-4-内酯（整体产率90%）、(S)-5-羟基-2-戊烯-4-内酯（整体产率86%）、(4S,5R)-5-羟基-2-己烯-4-内酯（整体产率86%）、(4R,5S)-5-羟基-2-己烯-4-内酯（整体产率82%）、(S)-伐索酸（整体产率58%）以及天然产物(5R,7S)-7-羟基-2-辛烯-5-内酯（优蔬内酯：整体产率20%）。

  The synthesis of 5- and 3-(1'-hydroxyalkyl)-substituted 5H-furan-2-ones 4a-d and 8a-d as well as 5-alkylidene-5H-furan-2-ones 5a-d is described. A study of the structure-activity relationship of these furanone-based natural product analogues towards two different quorum sensing systems is reported. Although the synthesized compounds are not as potent quorum sensing inhibitors as some natural counterparts and a synthetic analogue hereof, interesting structure-activity relationships are seen.

  Alkaline hydrolysis of 4-hydroxy- or/and 5-hydroxy-(2E)-alkenoate followed by acid treatment gave the corresponding (2E)-alkenoic acids which were subjected to lactone formation reaction without further purification. The crude acids were treated with 2,4,6-trichlorobenzoyl chloride in pyridine to afford γ-lactone or δ-lactone, respectively, accompanied by trans–cis isomerization. By this procedure, (±)-(4,5)-trans-5-benzyloxy-2-hexen-4-olide (90% overall yield), (S)-5-hydroxy-2-penten-4-olide (86% overall yield), (4S,5R)-5-hydroxy-2-hexen-4-olide (86% overall yield), (4R,5S)-5-hydroxy-2-hexen-4-olide (82% overall yield), (S)-parasorbic acid (58% overall yield) and natural product, (5R,7S)-7-hydroxy-2-octen-5-olide (euscapholide: 20% overall yield) were synthesized.
