An eco-friendly and simple procedure was proposed for the synthesis of 3,5-disubstituted 1,2,4-triazoles by optimized reaction of benzamidine hydrochloride and various aryl hydrazides. H2O and K2CO3 were applied as green and available solvent and base, respectively. The products were generated in good to high yields in one step and sufficient purity after a simple workup. The designed process is applicable
提出了一种生态友好且简单的方法,用于通过盐酸苄be与各种芳基酰肼的优化反应合成3,5-二取代的1,2,4-三唑。H 2 O和K 2 CO 3分别作为绿色和可用溶剂和碱。只需一步就可以生成高至高收率的产品,并且在简单的后处理后即可获得足够的纯度。设计的方法适用于其他有机合成,尤其是水溶性差的反应物(例如肼或酰肼)的合成。评价了所有制备的衍生物对10种致病菌菌株(包括革兰氏阳性和革兰氏阴性)以及2种霉菌和1种酵母菌株的抑制活性。制备的衍生物显示出良好的抗菌活性。在3位上含有2-羟基萘-3-基和5-氯噻吩-2-基取代基的1,2,4-三唑分别显示出最佳的抗真菌和抗菌性能。
