Heteroaryl substituted cyclopropyl ketones were prepared by reactions with Me 3SO+ I+, and by reaction with Lewis acids they were transformed into substituted dihydrobenzo[ b ]furanone or -thiophenone, or γ-hydroxy ketones. Cycloadditions with thiophene derivatives allowed the synthesis of substituted benzo[ b ]thiophene derivatives, but with poor yields. Structures and stereochemistry were established mainly
噻吩基和呋喃基丙烯酮与丙二酸酯,氰基乙酸酯和丙二腈反应,生成可环化为杂芳基取代的二氢吡喃,环己醇和哌啶酮的加成产物。杂芳基取代的环丙基酮是通过与 Me 3 SO + I +反应制备的 ,并且通过与 路易斯 酸反应,将 它们转化为取代的二氢苯并[ b ]呋喃酮或-噻吩酮或γ-羟基酮。与噻吩衍生物的环加成可以合成取代的苯并[ b ]噻吩衍生物,但收率很低。主要通过NMR光谱确定结构和立体化学。
