A green visible-light-promoted and electron donor-acceptor (EDA) complex-driven synthetic strategy for the construction of value-added naphtho[1',2':4,5]imidazo[1,2-]pyridines from 2-arylimidazo[1,2-]pyridines with -α-bromocinnamaldehydes has been accomplished under photocatalyst- and transition-metal-free conditions. This efficient annulation approach provides a new and straightforward pathway for the annulative π-extension of imidazo[1,2-]pyridine-based aromatics. Moreover, the sustainable methodology exhibits simple operation, a wide range of substrates, benign conditions, and good functional group compatibility.
一种绿色可见光促进且由电子供体-受体（EDA）络合物驱动的合成策略，用于在无光催化剂和过渡金属的条件下，由2-芳基咪唑并[1,2 - ]吡啶与-α-溴代肉桂醛构建增值萘并[1',2':4,5]咪唑并[1,2 - ]吡啶。这种高效的环化方法为基于咪唑并[1,2 - ]吡啶的芳烃的环化π-扩展提供了一条新的直接途径。此外，该可持续方法具有操作简单、底物范围广、条件温和以及官能团兼容性好等特点。
