  Synthesis and quantitative structure-activity relationships of antiallergic 2-hydroxy-N-(1H-tetrazol-5-yl)benzamides and N-(2-hydroxyphenyl)-1H-tetrazole-5-carboxamides

  摘要：

  The synthesis and antiallergic activity of a series of 2-hydroxy-N-1H-tetrazol-5-ylbenzamides and isomeric N-(2-hydroxyphenyl)-1H-tetrazole-5-carboxamides is described. A relationship between structure and intravenous antiallergic activity in the rat passive cutaneous anaphylaxis (PCA) test has been established using a Hansch/Free-Wilson model and used to direct studies toward potent derivatives. The contribution of physicochemical properties to activity is discussed. One member of this series, N-(3-acetyl-5-fluoro-2-hydroxyphenyl)-1H-tetrazole-5-carboxamide (3f), which was selected for further evaluation, has an ID50 value of 0.16 mg/kg po and is 130 times more potent than disodium cromoglycate (DSCG) on intravenous administration.

  Solid-Phase synthesis of new saphenamycin analogues with antimicrobial activity

  摘要：

  An array of 12 new saphenamycin analogues modified at the benzoate moiety was synthesized on solid support. Synthesis commenced with a chemoselective anchoring of saphenic acid through the carboxyl group to a 2-chlorotrityl functionalized polystyrene resin. The secondary alcohol was acylated in parallel with a series of differently substituted benzoic acid derivatives. Treatment with TFA-CH2Cl2 (5:995) released the expected saphenamycin analogues into solution. These new analogues were purified, characterized and screened for antimicrobial activity against Bacillus subtilis and Proteus mirabilis. Eight analogues exhibited MIC values against B. subtilis ranging from 0.07 to 3.93 mug/mL, comparable to the activities of previously reported saphenamycin analogues. (C) 2002 Elsevier Science Ltd.

  Treating the benzyl protected 3‐hydroxy‐1,3‐bis(2‐hydroxyphenyl)prop‐2‐en‐1‐ones solely with PhI(OAc)2 (PIDA) in DCE at room temperature readily furnished the seldom studied spiro‐2,2′‐benzo[b]furan‐3,3′‐ones in satisfactory to excellent yields. The hypervalent iodine reagent enables the metal‐free cascade spirocyclization resulting in the dual oxidative C−O bond formation.

  在室温下仅用PhI（OAc）2（PIDA）在室温下仅用PhI（OAc）2（PIDA）处理苄基保护的3-羟基-1,3-双（2-羟基苯基）丙-2-烯-1-酮很容易提供很少研究的spiro-2 ，2'-苯并[b]呋喃-3,3'-酮类产品具有令人满意的优异收率。高价碘试剂可实现无金属级联螺环化，从而形成双氧化C-O键。
