许多呈现出杀菌活性的化合物通常都具有一个含氮原子的杂环结构,诸如吡咯环。然而在实际应用的杀菌剂中,仅含有一个氧原子的杂环化合物仍十分有限。包含呋喃环结构的甲呋酰胺(fenfuram)、二甲呋酰胺(furcarbanil)和呋菌胺(methfuroxam);包含加氢呋喃环结构的呋菌唑(furconazole),以及含有一个二氧戊环结构的戊环唑(azaconazole)和丙环唑 Many of the compounds that exhibit bactericidal activity often have a nitrogen atom-containing heterocyclic structure, such as a pyrrole ring. However, in practical application of fungicides, heterocyclic compounds containing only one oxygen atom is still very limited. Fenfuram, furcarbanil and methfuroxam, which contain a furan ring structure; furconazole, which contains a furan ring structure, and furan ring which contains a dioxolane structure Azaconazole and propiconazole
