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.
