The 1,2,3-triazole ring fused with pyridine/pyrimidine was explored as new template for the identification of potential antimicrobial agents. The regioselective synthesis of these pre-designed N-heteroarenes was achieved via exploring the application of Buchwald’s strategy (i.e. C–N bond formation/reduction/diazotization/cyclization sequence) to the N-heteroarene system. Two of them showed promising antibacterial (comparable to streptomycin) and several showed potent antifungal (comparable to mancozeb) activities.

1,2,3-三唑与吡啶/嘧啶融合作为抗菌剂的新模板：区域选择性合成和强力N-杂芳烃的鉴定

探索与吡啶/嘧啶稠合的1,2,3-三唑环作为鉴定潜在抗菌剂的新模板。这些预先设计的N-杂芳烃的区域选择性合成是通过探索将Buchwald策略（即C–N键形成/还原/重氮化/环化顺序）应用于N-杂芳烃体系而实现的。它们中的两个显示出有希望的抗菌作用（与链霉素相当），另外几个显示出有效的抗真菌作用（与mancozeb相当）。
