  摘要：

  Introduction of selected amine containing side chains into the 3-position of N',2-diphenylquinoline-4-carbohydrazide based NK3 antagonists abolishes unwanted hPXR activation. Introduction of a fluorine at the 8-position is necessary to minimize unwanted hIK(r) affinity and a piperazine N-tert-butyl group is necessary for metabolic stability. The lead compound (8m) occupies receptors within the CNS following oral dosing (Occ(90) 7 mg/kg po; plasma Occgo 0.4 mu M) and has good selectivity and excellent PK properties. (c) 2006 Elsevier Ltd.

  Metal homoenolates are valuable synthetic intermediates which provide access to β-functionalized ketones. In this report, we disclose a Ni-catalyzed β-alkylation reaction of cyclopropanol-derived homoenolates using redox-active N-hydroxyphthalimide (NHPI) esters as the alkylating reagents. The reaction is compatible with 1°, 2°, and 3° NHPI esters. Mechanistic studies imply radical activation of the

  acetylacetonate [Fe(acac)3], the reaction of structurally diverse ketoxime esters with trimethylsilyl azide (TMSN3) afforded γ‐azido ketones in good to excellent yields. This unprecedented distal γ‐C(sp3)−H bond azidation reaction went through a sequence of reductive generation of an iminyl radical, 1,5‐hydrogen atom transfer (1,5‐HAT) and iron‐mediated redox azido transfer to the translocated carbon radical

  在催化量的乙酰丙酮铁（III）[Fe（acac）3 ]的存在下，结构多样的酮肟酸酯与三甲基硅烷基叠氮化物（TMSN 3）的反应可提供良好产率的γ-叠氮基酮。前所未有的远端γ-C（sp 3）-H键叠氮化反应经历了亚胺基的还原生成，1,5-氢原子转移（1,5-HAT）以及铁介导的氧化还原叠氮基转移至易位的碳自由基。TMSN 3不仅用作功能化未激活的C（sp 3）-H键的氮源，而且还用作还原剂以原位生成催化活性的Fe II。基于相同的原理，一种新颖的β-C（sp3）-H通过N-酰氧基酰亚胺的醇官能化随后被实现，在将所得的酯水解后，导致β-叠氮基醇，这是有机和药物化学的重要组成部分。
