  Fluorinated Phenylcyclopropylamines. 2. Effects of Aromatic Ring Substitution and of Absolute Configuration on Inhibition of Microbial Tyramine Oxidase

  摘要：

  A series of para-substituted diastereopure cis- and trans-2-fluoro-2-arylcyclopropylamines were synthesized and these were investigated as inhibitors of microbial tyramine oxidase from Arthrobacter sp. All compounds were shown to be competitive inhibitors of this enzyme. The nature of the para-substituents in the more potent trans-isomer (cis-relationship between fluorine and the amino group) of 2-fluoro-2-arylcyclopropylamine influenced the inhibitory potency in a consistent fashion. Thus, electron-withdrawing groups (F, Cl) slightly decreased the activity, while the methyl group (+ I substituent) increased the activity by a factor of ca. 7 compared to trans-2-fluoro-2-phenylcyclopropylamine and by a factor of 90 compared to tranylcypromine. Activity also was strongly dependent on the absolute configuration. The (1S,2S)-enantiomer of 2-fluoro-2-phenylcyclopropylamine was an excellent inhibitor of tyramine oxidase whereas the (1R,2R)-enantiomer was essentially devoid of activity.

  Asymmetric Cyclopropanation of Vinyl Fluorides: Access to Enantiopure Monofluorinated Cyclopropane Carboxylates

  摘要：

  过渡金属催化的环丙烷化反应，通过与烷基二氮酸酯的反应，能够平稳地获得由烃基醇或芳香族乙烯氟化物（由相应烯烃经过溴氟化和后续去溴化反应制得）的外消旋1 : 1混合物的顺/反凉氟化环丙烷羧酸酯。采用手性纯双（噁唑啉）配体和铜（I）三氟甲磺酸盐使得该反应具备顺式立体选择性和对映选择性。例如，α-氟苯乙烯（3a）与叔丁基二氮酸酯在以(S)-叔亮氨酸为基础的催化剂11b和CuOTf的存在下反应，得到4 : 1的反-2-氟-2-苯基环丙烷羧酸酯（4e），其对映体过量率（ee）为93%，以及相应的顺式异构体5e，其对映体过量率为89%。反式异构体4e的绝对构型已经通过衍生物的X射线结构分析确定为（1S，2S）。

  Monofluorinated cyclopropanecarboxylates are available in racemic or optically active form by transition metal-catalyzed reactions of vinylfluorides with diazoacetates. From α-fluorostyrene and tert-butyl diazoacetate in the presence of 2 mol% of an enantiopure bis(oxazoline) copper complex, a 81:19 mixture of tert-butyl trans- and cis-2-fluoro-2-phenylcyclopropanecarboxylates was obtained with high

  s and 2-fluoro-2-phenylcyclopropylalkylamines, as well as 2-fluoro-1-phenylcyclopropylamines and 2-fluoro-1-phenylcyclopropylmethylamines, were synthesized in order to study the effects of fluorine substitution on monoamine oxidase inhibition. Inhibitory activity was assayed using commercially available microbial tyramine oxidase. Characterization of tyramine oxidase, carried out prior to the inhibition

  为了研究效果，合成了两个非对映体纯的苯基环丙胺类似物2-氟-2-苯基环丙胺和2-氟-2-苯基环丙基烷基胺，以及2-氟-1-苯基环丙胺和2-氟-1-苯基环丙基甲胺。取代对单胺氧化酶抑制的影响 使用可商购的微生物酪胺氧化酶测定抑制活性。在抑制实验之前进行酪胺氧化酶的表征，证实了较早的建议，即该酶是对氨基脲敏感的含铜单胺氧化酶。最有效的竞争性抑制剂是反式-2-氟-2-苯基环丙胺，其IC（50）值比非氟化化合物tranylcypromine低10倍。发现2-氟-1-苯基环丙基甲基胺是酪胺氧化酶的弱非竞争性抑制剂。直接与环丙烷环键合的游离氨基和与氨基成顺式关系的氟原子的存在是增加酪氨酸氧化酶抑制作用的结构特征。

  Solid state structures of a selection of 2-fluoro-2-phenylcyclopropane derivatives were examined by X-ray crystallography in order to identify short intermolecular contacts of C-F groups to H-X moieties (X = C, N). Particularly, several cis-configured fluorinated phenylcyclopropane derivatives showed extremely close intermolecular contacts. The shortest of such C-(HF)-F-...-C-distances (2.17 angstrom, C-F-H angle 162 degrees) was found in (IS,2R)-(2-fluoro-2-phenylcyclopropyl)methyl N-(4-bromophenyl)carbamate (8) and the closest N-(HF)-F-...-C-interaction (2.01 angstrom, C-F-H angle 167 degrees) was found in (+/-)-cis-2-fluoro-2-phenylcyclopropyl carboxamide (4). Comparison of the structures of several of the fluorinated cyclopropares with those of the non-fluorinated counterparts revealed that close intermolecular contacts of fluorine substituents to hydrogen atoms are not solely due to crystal packing effects, but are also caused by weak X-H...
