Synthesis of novel substituted tetrazoles having antifungal activity
摘要:
In an effort to find potent antifungal agents, a variety of triazole derivatives with a 5-substituted tetrazole structure 6, 7, 12 and 14 were prepared and evaluated for antifungal activity against Candida spp., Cryptococcus neoformans, and Aspergilhis spp. in vitro. The location of the methyl group at the C-3 of compounds 12 and 14 has been demonstrated to be a key structural element of antifungal potency. (C) 2004 Elsevier SAS. All rights reserved.
Cu/Graphene/Clay Nanohybrid: A Highly Efficient Heterogeneous Nanocatalyst for Synthesis of New 5-Substituted-1<i>H</i>-Tetrazole Derivatives Tethered to Bioactive<i>N</i>-Heterocyclic Cores
bioactive N‐heterocyclic cores were synthesized through [3 + 2] cycloadditionreactions between alkyl nitriles (RCN) and NaN3 in the presence of Cu/aminoclay/reduced graphene oxide nanohybrid (Cu/AC/r‐GO nanohybrid) as a heterogeneous nanocatalyst in water/i‐PrOH (50:50, V/V) media at reflux condition. The influence of factors on a sample reaction including solvent type, temperature, and catalyst amount
在存在铜/氨基粘土/还原氧化石墨烯纳米杂化物(铜)的情况下,通过烷基腈(RCN)和NaN 3之间的[3 + 2]环加成反应,合成了一系列具有生物活性N杂环核的5位取代的1 H-四唑。/ AC / R-GO纳米杂化物)作为在水中的纳米催化剂的异构/我‐PrOH(50:50,V / V)介质在回流条件下。讨论了因素对样品反应的影响,包括溶剂类型,温度和催化剂用量。该当前协议具有许多优点,包括价格便宜,对环境无害,基材范围广,产率高以及易于处理。该协议中使用的Cu / AC / r-GO是一种低成本催化剂,被证明具有相当大的化学和热稳定性。这种非吸湿性催化剂可以轻松回收,再利用和存储,以进行许多连续的反应,而不会显着降低反应活性。
