palladium-catalyzed approach has been developed for the synthesis of 5-amino-1,2,4-oxadiazoles from amidoximes and isocyanides. Various 5-amino-1,2,4-oxadiazoles were obtained in moderate to high yields under mild conditions. The key to the success of this strategy involves new C–N bond and C–O bond formation via palladium-catalyzed isocyanide insertion.
已经开发了一种方便有效的钯催化方法,用于由a肟和异氰酸酯合成5-氨基1,2,4-恶二唑。在温和条件下以中等至高收率获得了各种5-氨基-1,2,4-恶二唑。该策略成功的关键在于通过钯催化的异氰酸酯插入形成新的C–N键和C–O键。
