  摘要：

  通过对70对异构化的烯丙基苯基醚（a）和（Z）-丙-1-烯基苯基醚（b）在DMSO溶液中的化学平衡研究，考察了它们相对热力学稳定性的变化。从平衡常数随温度的变化中，评估了在298.15 K下的异构化吉布斯自由能、焓和熵。由于其低焓值，（Z）-丙-1-烯基苯基醚在平衡状态下具有显著优势，a→b异构化的吉布斯自由能范围从-12至-23 kJ/mol。在大多数反应中，熵的贡献可以忽略不计，但偶尔会发现小于+10 J/K·mol的正值。平衡研究还扩展到涉及两对在烯键C(2)位置带有甲基取代基的相关异构化醚。甲基取代基可以增加烯丙基醚的相对热力学稳定性约3.4 kJ/mol。

  anti-homoallylic alcohols allow the synthesis of the desired skeleton in a stereoselective fashion. As an illustration, we used this strategy for the preparation of the dihydrodehydrodiconiferyl alcohol (1a), a natural dihydrobenzofuran neolignan, as well as for a formal synthesis of its O-demethylated derivative 1b.
