我们报告了一种温和且操作简单的烯烃三氟酰化策略,该策略利用三氟乙酸酐作为低成本且易于获得的试剂。这种光介导的过程与传统方法有着根本的不同,它通过由光催化剂促进的三氟酰基自由基机制发生,从而触发 CO 键断裂。机理研究(动力学同位素效应、光谱电化学、光谱学、理论研究)突出了转瞬即逝的 CF 3的证据光氧化还原条件下的 CO 自由基。三氟酰基自由基可以在 CO 气氛下稳定,提供具有更高化学效率的三氟乙酰化产物。此外,该方法可以通过简单地改变反应参数变成三氟甲基化协议。除了简单的烯烃外,该方法还允许小分子药物和常见药效团的化学和区域选择性功能化。
Preparation of homochiral crown ether containing (S)-1-(1-adamantyl)ethane-1,2-diol as a chiral subunit and its enantioselective complexation with an organic ammonium cation
Homochiral 1-(1-adamantyl)ethane-1,2-diol(5) was prepared and its absolute configuration was determined to be (S)-(+)-5 by enzymatic and H-1 n.m.r. spectroscopic methods. Using (S)-(+)-5 as a chiral subunit, the homochiral crown ether (+)-18 was synthesized and its enantioselectivity in complexation of methionine methyl ester perchlorate was also examined by the H-1 n.m.r. spectroscopic method.
