Design, Synthesis and Antibacterial Activity of Novel Pyrimidine‐Containing 4H‐Chromen‐4‐One Derivatives**

A series of pyrimidine‐containing 4 H ‐chromen‐4‐one derivatives were designed and synthesized by combining bioactive substructures. Preliminary biological activity results showed that most of the compounds displayed significant inhibitory activities in vitro against Xanthomonas axonopodis pv. Citri ( X. axonopodis ), Xanthomonas oryzae pv. oryzae ( X. oryzae ) and Ralstonia solanacearum ( R. solanacearum ). In particular, compound...
