Synthesis of 2,3-dihydro-1H-pyrrolo[1,2-a]benzimidazoles via the cyclopropyliminium rearrangement of substituted 2-cyclopropylbenzimidazoles
摘要:
2-Cyclopropylbenzimidazole derivatives with various substituents in the small ring undergo cyclopropyliminium rearrangement into 2,3-dihydropyrrolobenzimidazoles substituted at positions 1, 2 or 3. The substrates containing a functional group in position 1 of the cyclopropane ring form products substituted at position 3. Substituents at position 2 in most cases lead to the formation of a mixture of isomers. The reaction can be directed to yield one of the isomers predominantly by varying the solvent polarity.

The C–C bond in non-activated cyclopropanes can be intramolecularly cleaved with an electrochemically generated amidyl radical forming oxazolines. In the presence of TBABF4, this provides 1,3-oxyfluorination products. C–C bond cleavage of cyclopropane proceeds with inversion of the configuration, suggesting an intramolecular homolytic substitution (SHi) mechanism. The performance of TBABF4 as an efficient
未活化的环丙烷中的 C-C 键可以通过电化学产生的酰胺基自由基在分子内裂解,形成恶唑啉。在TBABF 4存在下,这提供1,3-氧氟化产物。环丙烷的 C-C 键断裂随着构型的反转而进行,表明存在分子内均裂取代 (S H i) 机制。 TBABF 4作为有效氟化物源的性能可以通过 BF 4 -阴离子在阳极表面的积累来解释,在阳极表面,通过以 C 为中心的自由基的氧化形成碳正离子。
