A gold-catalyzed regioselective heteroannulation strategy has been developed for the concise and efficient synthesis of imidazo[1,2-a]pyrazinones. The protocol allows the introduction of diversity via the application of substituted propargyl amines or via Suzuki-coupling of the generated imidazo[1,2-a]pyrazinones with various (het)aryl boronic acids.
已经开发了一种金催化的区域选择性异环化策略,用于简洁有效地合成咪唑并[1,2- a ]吡嗪酮。该协议允许通过应用取代的炔丙基胺或通过将生成的咪唑并[1,2- a ]吡嗪酮与各种(杂)芳基硼酸进行铃木偶联来引入多样性。
