  Trans-4-aminoproline, a phytotoxic metabolite with herbicidal activity produced by Ascochyta caulina

  摘要：

  A phytotoxic metabolite, characterized through NMR techniques and synthetic methods as trans-4-aminoproline, was isolated from the culture filtrates of Ascochyta caulina, a promising mycoherbicide for biological control of Chenopodium album. The metabolite, which shows interesting phytotoxic properties, together with ascaulitoxin (recently characterized as N-2-beta-D-glucoside of the unusual bis-amino acid 2,4,7-triamino-5-hydroxyoctandioc acid) and another unidentified compound, compose an active fraction of A. caulina culture filtrates with promising herbicidal properties. When assayed on leaves of host and non host dicots, including wild and cultivated plants, the trans-4-aminoproline showed a wide range of toxicity, with leaves of C. album being the most sensitive. Other interesting aspects were its inefficacy on several monocots, both cultivated and wild and its lack of antifungal, antibiotic and zootoxic activities. This is the first report on trans-4-aminoproline as naturally occurring compound and phytotoxic metabolite produced by A. caulina. (C) 2000 Elsevier Science Ltd. All rights reserved.

  asymmetric Staudinger–aza-Wittig reaction of (o-azidoaryl)malonates, allowing access to chiral quaternary oxindoles through phosphine oxide catalysis. We designed a novel HypPhos oxide catalyst to enable the desymmetrizing Staudinger–aza-Wittig reaction through the PIII/PV═O redox cycle in the presence of a silane reductant and an IrI-based Lewis acid. The reaction occurs under mild conditions, with

  本文描述了(邻叠氮基芳基)丙二酸酯的催化不对称施陶丁格-氮杂-维蒂希反应，允许通过氧化膦催化获得手性季羟吲哚。我们设计了一种新型 HypPhos 氧化物催化剂，可在硅烷还原剂和 Ir I基路易斯酸存在下通过 P III /P V =O 氧化还原循环实现去对称 Staudinger-aza-Wittig 反应。该反应条件温和，官能团耐受性好，底物范围广，具有优异的对映选择性。密度泛函理论表明，去对称反应中的对映选择性源于 Ir I物种和 HypPhos 催化剂的协同作用。该方法的实用性通过七种生物碱靶标的（正式）合成得到证明：(−)-胶粘蛋白 C、(−)-coerulescine、(−)-horsfiline、(+)-deoxyeseroline、(+)-esermethole、( +)-毒扁豆碱和(+)-毒扁豆碱。

  A series of new sulfonyl pyrrolidine derivatives was designed, synthesized, and assayed for their inhibitory activities on matrix metalloproteinase 2 (MMP-2) and aminopeptidase N (AP-N). The results showed that these pyrrolidine derivatives exhibited highly selective inhibition against MMP-2 as compared with AP-N. The compounds 4c, 4j, 5a, and 5b were equally or more potent MMP-2 inhibitors than the positive control LY52. The FlexX docking was done to explain the reason for the different potency between MMP-2 and AP-N. Structure-activity relationships were also briefly discussed. (C) 2008 Elsevier Ltd.

  trans-4-hydroxy-L-proline (5) has been elaborated into a new series of pyrrolidine-L-nucleoside analogues incorporating non-standard 5-substituted-pyrimidine nucleobases, via the azidopyrrolidines 12 and 13. Those analogues employing an acyl protecting group on the primary hydroxyl functionality underwent radical bromination of the ethyl side chain of the pyrimidine ring, to provide E-5-(2-bromovinyl)uracil-pyrrolidine-L-nucleosides 23-26. Of the compounds assessed for potential antiviral activity only 5-ethyluracil-(benzoyloxymethyl)pyrrolidine 20 was found to be a specific inhibitor of vaccinia virus. (C) 1998 Elsevier Science Ltd.
