  2,3,4,4a,5,9b-Hexahydro-1H-indeno[1,2-b]pyridines: potential antidepressants

  摘要：

  The synthesis of various diastereoisomeric H4a,H5-cis,H4a,H9b-cis- and H4a,H5-trans,H4a,H9b-cis-2,3,4,4a,5,9b-hexahydro -1H-indeno[1,2-b]pyridines is described, as well as the evaluation of their antidepressant potency. Elucidation of structure-activity relationships revealed the H4a,H5-trans compounds as being by far the more active of the two series of diastereoisomers. Pharmacological and biochemical data suggest that these compounds are potential antidepressants with central stimulating properties, which are characterized by strong norepinephrine and dopamine reuptake inhibition.

  (Phenylmethoxy)phenyl derivatives of w-oxo- and w-tetrazolylalkanoic acids and related tetrazoles. Synthesis and evaluation as leukotriene D4 receptor antagonists

  摘要：

  Two series of (phenylmethoxy)phenyl compounds derived from the structure of LY163443 were synthesized and evaluated as leukotriene D4 receptor antagonists. In the OMEGA-[(phenylmethoxy)phenyl]-OMEGA-oxoalkanoic acid series, 5-[4-[(4-acetyl-2-ethyl-3-hydroxyphenyl)methoxy]phenyl]-3,3-dimethyl-5-oxopentanoic acid (8) was the most potent antagonist of LTD4-induced contractions of guinea pig ileum (pK(B) of 7.60) and LTD4 pressor response in pithed rats (ED50 of 1.4 mg/kg iv). Replacing the carboxylic acid function with 5-tetrazole gave slightly more potent compounds. In the OMEGA-[5-[[(phenylmethoxy)phenyl]alkyl]tetrazolyl]alkanoic acid series, replacing the carboxylic acid with 5-tetrazole gave compounds that were equally effective in the guinea pig ileum but more potent in vivo against the LTD4 pressor response in rat. The pK(B) value in the guinea pig ileum for 1-[2-hydroxy-3-propyl-4-[[4-[[2-[3-(1H-tetrazol-5-yl)propyl]-2H-tetrazol-5-yl]methyl]phenoxy]methyl]phenyl]ethanone (25) was 7.87 and the ED50 for antagonism of the LTD4 pressor response was 4.0 mg/kg iv. The sodium salts of 8 (9) and 25 (26) given by the iv route of administration antagonized LTD4-induced cardiovascular alterations in anesthetized rat and LTD4-induced bronchoconstriction in guinea pig in a dose-dependent manner. Oral activity was also demonstrated against the LTD4-induced bronchoconstriction in guinea pig.

• Enantioselective Titanium(III)‐Catalyzed Reductive Cyclization of Ketonitriles
  作者：Jan Streuff、Markus Feurer、Plamen Bichovski、Georg Frey、Urs Gellrich

  Reduction, please! The title reaction affords α‐hydroxyketones, a common structural motif in biologically active natural products, in good yields and high enantioselectivities at room temperature. The commercially available ansa‐titanocene 1 was found to be an efficient catalyst for this process, which presumably proceeds by addition of a ketyl radical to a nitrile.

  请减少！标题反应可在室温下以高收率和高对映选择性提供α-羟基酮，这是生物活性天然产物中常见的结构基序。人们发现市售的ansa-titanocene 1是该过程的有效催化剂，据推测可通过向腈中添加酮基来进行。

Notably, complete regioselectivity can be achieved in this C–C bond cleavage reaction, providing an efficient access to a variety of cyanoketones under cyanide-free conditions. A radical reaction pathway was proposed on the basis of the results of the mechanistic probing experiments.

  cyano C1 unit and ethynyl C2 unit are regiospecifically introduced to the γ‐position of ketones at room temperature, providing a mild yet powerful method for production of elusive aliphatic nitriles and alkynes. All transformations described are based on a common sequence: 1) oxidative ring‐opening of cyclobutanol substrates by C−C bond cleavage; 2) radical addition to triple bonds bearing an arylsulfonyl
