  室温下α-氟代烷基醇的有机催化好氧氧化为氟代烷基酮

  摘要：

  描述了缺电子的α-氟代烷基醇在室温下的有机催化好氧氧化。所得的氟代烷基酮是多种含氟分子的通用合成中间体。现在，这种困难的转化是通过α-氟代烷基醇与N-氧基自由基的反应完成的，该自由基是由9-氮杂双环[3.3.1]壬基-3-酮N-氧基/氮氧化物（酮基ABNO / NO）催化生成的X）和氧气在乙酸（AcOH）中的反应，以高收率得到相应的氟代烷基酮。该操作简单的反应可以在温和的条件下进行，并且已应用于多种醇（20种实例），因此证明了对官能团的高耐受性。此外，基于此方法的改进的一锅操作规程能够将克转化为醛，将醛转化为三氟甲基酮。

  affected by the nature and chirality of the dopant. The hexaimine macrocycles after reduction of the CN imine bonds formed trianglamines – useful chiral ligands in stereoselective synthesis. The Zn–trianglamine complexes were employed as catalysts for asymmetric hydrosilylation of prochiral ketones, providing products of enantiomeric excess up to 98%. This remains the best result obtained for Zn–diamine

  The synthesis of a new trifluoromethyl oxetane was developed using a Corey–Chaykovsky epoxidation/ring‐expansion reaction of trifluoromethyl ketones. The reaction was shown to proceed under mild conditions and displays a broad substrate scope. The trifluoromethyl oxetane was also evaluated as a tert‐butyl isostere in the context of the γ‐secretase modulator (GSM) program. We demonstrate that the trifluoromethyl

  新的三氟甲基氧杂环丁烷的合成是利用三氟甲基酮的Corey–Chaykovsky环氧化/扩环反应开发的。该反应显示在温和条件下进行，并显示出较宽的底物范围。在γ-分泌酶调节剂（GSM）程序的背景下，三氟甲基氧杂环丁烷也被评估为叔丁基异戊二烯。我们证明，相对于相应的叔丁基GSM类似物，含三氟甲基氧杂环丁烷的GSM降低了亲脂性，提高了亲脂性效率（LipE）和代谢稳定性，因此突出了三氟甲基氧杂环丁烷作为极性更强的叔丁基等排烷的若干益处。
