  转氨酶作为合成对映体纯 β,β-二氟胺的合适催化剂

  摘要：

  转氨酶已显示出催化一系列脂肪族和（杂）芳香族 α,α-二氟代酮胺化的能力，具有高立体选择性，从而以高分离产率 (55–82%) 提供相应的 β,β-二氟胺和优异的对映体过量 (>99%)。还观察到，这些活化的底物可以通过使用少量摩尔过量的胺供体来定量转化，因为这种胺化过程在热力学上是有利的。选定的转化可以放大到 500 mg，显示了这种方法的稳健性。

  An Acetal Acylation Methodology for Producing Diversity of Trihalomethyl- 1,3‑dielectrophiles and 1,2-Azole Derivatives

  摘要：

  A series of functionalized 1,1,1-trihalo-4-methoxy-3-alken-2-ones [CX3C(O)CR1=CROMe, where X = F or Cl; R = n-heptyl, n-octyl, n-nonyl, n-decyl, n-undecyl, n-tridecyl, (CH2)(2)CH=C(Me)(2), (CH2)(2)Ph, (CH2)(2)-(4-HOC6H4), (CH2)(2)-(4-MeOC6H4), (CH2)(2)CO2Me, (CH2)(3)CO2Me, CH(SMe)CH3, CH2(2-MeOC6H4), and R-1 = H, and R = H and R-1 = n-decyl] were synthesized from respective alkyl methyl ketones or aldehyde via acetal acylation using trifluoroacetic anhydride and trichloroacetyl chloride. 1,1,1-Trihalo-4-methoxy-3-alken-2-ones with acid-compatible substituents were easily hydrolyzed to respective trihalomethyl-1,3-diketones. The 1,1,1-trihalo-4-methoxy-3-alken-2-ones and/or respective trihalomethyl-1,3-diketones were reacted regiospecifically with hydroxylamine hydrochloride, leading to isoxazole derivatives, and with hydrazines, leading to respective 1H-pyrazole derivatives. The structures of all compounds were assigned based on nuclear magnetic resonance (NMR) and mass spectrometric data. This method represents an efficient pathway for the regioselective trihaloacetylation of asymmetrically substituted alkyl methyl ketones and highly self-condensing aldehydes. Moreover, this approach allows the introduction of biologically recognizable moieties, such as those from levulinic acid, sulcatone (prenyl), benzylacetone, anisylacetone, and raspberry ketone, as synthetic molecular targets.
