The compound, 2H-pyrrole, is a key scaffold contained in natural products, bioactive compounds, pharmaceuticals, and organic functional materials. However, the development of efficient synthetic strategies for 2H-pyrroles is challenging. This is because 2H-pyrroles, owing to their nonaromatic nature, are easily converted into the thermodynamically more stable 1H-pyrroles. Recently, efficient and straightforward synthetic strategies for 2H-pyrroles have been developed, including the dearomatization of 1H-pyrrole, oxidation of pyrrolines or pyrrolidines, ring construction via catalytic cycloaddition, and rearrangement of 3H-pyrroles. In this review, we summarize the progress in the research on 2H-pyrrole synthesis since 2000 and briefly discuss the synthesis reaction mechanisms.

2H-吡咯合成方法的最新进展

该化合物 2 H-吡咯是天然产物、生物活性化合物、药物和有机功能材料中的关键支架。然而,开发 2 H-吡咯的有效合成策略具有挑战性。这是因为2 H-吡咯由于其非芳香性质,很容易转化为热力学上更稳定的1 H-吡咯。最近,已经开发了2 H-吡咯的高效且简单的合成策略,包括1 H-吡咯的脱芳构化、吡咯啉或吡咯烷的氧化、通过催化环加成的环构建以及3 H-吡咯的重排。本文综述了2000年以来2H-吡咯合成的研究进展,并简要讨论了合成反应机理。
