Pyrroles are important N-heterocycles found in medicines and materials. The formation of pyrroles from widely accessible pyrrolidines is a potentially attractive strategy but is an underdeveloped approach due to the sensitivity of pyrroles to the oxidative conditions required to achieve such a transformation. Herein, we report a catalytic approach that employs commercially available B(C6F5)3 in an
吡咯是在药物和材料中发现的重要的N-杂环化合物。从广泛使用的吡咯烷中形成吡咯是一种潜在有吸引力的策略,但由于吡咯对实现这种转化所需的氧化条件的敏感性,该方法尚未成熟。在此,我们报告了一种催化方法,该方法在操作简单的过程中采用市售的 B(C 6 F 5 ) 3 ,允许吡咯烷作为吡咯的直接合成子。机理研究揭示了对硼烷催化脱氢过程的见解。
