and methyl-bearing pyrazoline, pyrrole, or thiophene ring in the acid component, mimicking similar-substituted pyrazole carboxamides. As five-membered heterocyclic systems with such a special substitution pattern are barely known, unique synthesis routes had to be developed, which rely, e.g., on the van Leusen pyrrole synthesis and the halogen dance reaction. Synthesis and biological activity against
摘要已经制备了新型的具有杀真菌活性的琥珀酸脱氢酶抑制剂,其在酸组分中带有带有二氟甲基和甲基的吡唑啉,吡咯或噻吩环,模仿相似取代的吡唑羧酰胺。由于具有这种特殊取代模式的五元杂环系统是鲜为人知的,因此必须开发独特的合成路线,其依赖于例如范·劳森吡咯的合成和卤素舞反应。报道了这些二氟甲基化吡唑啉,吡咯和噻吩衍生物的合成和针对选定的子囊菌病原体的生物学活性。 图形概要
