  Synthesis, biological evaluation, and preliminary structure-activity considerations of a series of alkylphenols as intravenous anesthetic agents

  摘要：

  Following our discovery of the intravenous (iv) anesthetic activity of 2,6-diethylphenol in mice, a series of alkylphenols was examined in this species and the most active analogues were further evaluated in rabbits. The synthesis of compounds which were not commercially available was accomplished by adaptations of standard ortho-alkylation procedures for phenols. Structure-activity relationships were found to be complex, but, in general, potency and kinetics appeared to be a function of both the lipophilic character and the degree of steric hindrance exerted by ortho substituents. The most interesting compounds were found in the 2,6-dialkyl series, and the greatest potency was associated with 2,6-di-sec-alkyl substitution. In particular, 2,6-diisopropylphenol (ICI 35 868) emerged as a candidate for further development and has subsequently been shown to be an effective iv anesthetic agent in man.

  Thermodynamic, spectroscopic, and density functional theory studies of allyl aryl and prop-1-enyl aryl ethers. Part 1. Thermodynamic data of isomerization

  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。

  A chemical equilibration study of the relative thermodynamic stabilities of seventy isomeric allyl aryl ethers (a) and (Z)-prop-1-enyl aryl ethers (b) in DMSO solution has been carried out. From the variation of the equilibrium constant with temperature the Gibbs energies, enthalpies, and entropies of isomerization at 298.15 K have been evaluated. Because of their low enthalpies, the (Z)-prop-1-enyl aryl ethers are strongly favored at equilibrium, the Gibbs energies of the a→b isomerization ranging from −12 to −23 kJ mol−1. The entropy contribution is negligible in most reactions, but occasionally small positive values less than +10 J K−1 mol−1 of the entropy of isomerization are found. The equilibration studies were also extended to involve two pairs of related isomeric ethers with a Me substituent on C(2) of the olefinic bond. The Me substituent was found to increase the relative thermodynamic stability of the allylic ethers by ca. 3.4 kJ mol−1.
