  Lewis Acid Promoted Reactions of Ethenetricarboxylates with Allenes: Synthesis of Indenes and γ-Lactones via Conjugate Addition/Cyclization Reaction

  摘要：

  Indenes are important core structures in organic chemistry. Few simple arylallenes have been used to construct indene skeletons by Friedel Crafts reaction. Lewis acid catalyzed reaction of ethenetricarboxylates 1 and arylallenes has been examined in this study. The reaction of arylallenes and ethenetricarboxylate triesters with SnCl4 gave indene derivatives efficiently, via a conjugate addition/Friedel-Crafts cyclization reaction. On the other hand, the reactions of 1,1-diethyl 2-hydrogen ethenetricarboxylate and arylallenes or alkylallenes with SnCl4 at -78 degrees C or room temperature and subsequent treatment with Et3N gave gamma-lactones. The reactions of triethyl ethenetricarboxylate and 1,1-dialkylallenes with SnCl4 at room temperature also gave gamma-lactones.

  Method to inhibit ethylene responses in plants

  摘要：

  本发明一般涉及抑制植物和植物材料中乙烯反应的方法，特别涉及通过将植物暴露于环丙烯衍生物和其组合物中来抑制各种乙烯反应，包括植物成熟和降解，其中：1）环丙烯环上至少一个取代基含有碳环或杂环，或2）一个取代基含有硅、硫、磷或硼，或3）至少一个取代基含有一到四个非氢原子，且至少一个取代基含有多于四个非氢原子。
