A short and efficientsynthesis of substituted pyrroles was accomplished in good yields via the novel coupling cyclization reaction of 1,3-diketones with imines promoted by low-valenttitaniumreagent. High regioselectivity was achieved and the structures of two of the products were confirmed by X-ray diffraction studies.
通过低价钛试剂促进的 1,3-二酮与亚胺的新型偶联环化反应,以良好的收率完成了取代吡咯的短而有效的合成。实现了高区域选择性,并且通过 X 射线衍射研究证实了两种产物的结构。
