Synthesis of new pyrrolo[1,2-a]quinoxalines: potential non-peptide glucagon receptor antagonists
摘要:
Synthesis of new pyrrolo[1,2-a]quinoxaline derivatives was achieved starting from various nitroanilines or orthophenyle- nediamines. Their affinity towards glucagon receptors was evaluated. (C) Elsevier, Paris.

We report herein a method for the synthesis of 1-arylsulfonyl pyrrolo[1,2-a]quinoxalines. The process included electrophilic iodination with N-iodosuccinimide of pyrrolo[1,2-a]quinoxalines and a copper-catalyzed sulfonylation with sodium aryl sulfinates. An array of functionalities including ester, nitro, and ketone groups are tolerated under reaction conditions. Two possibilities to rationalize the
我们在此报道了一种合成1-芳基磺酰基吡咯并[1,2- a ]喹喔啉的方法。该方法包括用吡咯并[1,2- a ]喹喔啉的N-碘代琥珀酰亚胺进行亲电碘化,以及用芳基亚磺酸钠进行铜催化的磺酰化。在反应条件下可以耐受一系列官能团,包括酯、硝基和酮基团。考虑了使磺酰化机制合理化的两种可能性。
