A simple approach for synthesis of novel aza-fused scaffolds such as pyrido[1,2-α]benzimidazoles and imidazo[1,2-α]pyridines was developed by Rh(III)-catalyzed direct oxidative coupling between alkenes and unactivated alkynes without an extra directing group. The method would allow a broad substrate scope, providing fused heterocycles with potential biological properties.
通过Rh(III)催化的烯烃与未活化炔烃之间的直接氧化偶联,开发了一种简单的合成新型氮杂稠合骨架的方法,如吡啶并[1,2- α ]苯并咪唑和咪唑并[1,2- α ]吡啶一个额外的指导小组。该方法将允许广泛的底物范围,提供具有潜在生物学特性的稠合杂环。
