An efficient, convenient short syntheticprocedure for the synthesis of the intricate 5A5B6C-ring fusion topologies of tricyclic spiranoid β-hydroxybutyrolactones through lactonization of the key intermediate trans-α-hydroxyindenones with malonates is described. All the compounds synthesized exhibited environmentally benign characteristics, moderate fungicidal, nematocidal, and anti-TMV activities
描述了通过关键的中间反式-α-羟基茚满酮与丙二酸酯的内酯化来合成三环螺环状β-羟基丁内酯的复杂的5 A 5 B 6 C环稠合拓扑结构的高效,便捷的合成方法。合成的所有化合物均表现出对环境无害的特性,中等的杀真菌,杀线虫和抗TMV活性。
