  Unexpected C–C Bond Cleavage: A Route to 3,6-Diarylpyridazines and 6-Arylpyridazin-3-ones from 1,3-Dicarbonyl Compounds and Methyl Ketones

  摘要：

  An unexpected C-C bond cleavage has been revealed in the absence of metal. This observation has been exploited to develop an efficient approach toward 3,6-iarylpyridazines and 6-arylpyridazin-3-ones from simple and commercially available 1,3-dicarbonyl compounds and methyl ketones.

  A highly efficient method for the construction of 3a,6a-dihydrofuro[2,3-b]furan derivatives has been developed via a novel bicyclization, which is very valuable for the synthesis of fused furofuran compounds since it is time-saving and catalyst-free. Based on the bicyclization, a coupled domino strategy has been developed to directly construct 3a,6a-dihydrofuro[2,3-b]furan derivatives from methyl ketones

• Brønsted acid promoted addition–cyclization and C–C bond cleavage: a convenient synthesis of 2-amino-5-aroylmethylthiazoles derivatives

  日期：——

  A Brønsted acid promoted C–C bond cleavage method for the synthesis of novel 2-amino-5-aroylmethylthiazole derivatives has been directly developed from 1,4-enediones and thioureas through self-sequenced thio-Michael-addition, intramolecular selective cyclization, dehydration/aromatization, and C–C bond cleavage reactions. It is noteworthy that this reaction has significant advantages in simple reagents, under environmentally benign conditions and with excellent yields. This highly efficient method is also a highly attractive alternative for the preparation of PLTP, CETP inhibitors and novel biheterocycles.

  通过自序的硫代迈克尔加成反应、分子内选择性环化反应、脱水/芳香化反应和 CâC 键裂解反应，从 1,4-enediones 和硫脲类化合物直接开发出了一种布氏酸促进的 CâC 键裂解方法，用于合成新型 2-amino-5-aroylmethylthiazole 衍生物。值得注意的是，该反应具有试剂简单、环境友好、收率高的显著优势。这种高效的方法也是制备 PLTP、CETP 抑制剂和新型生物杂环的极具吸引力的替代方法。
