So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Huang, En-He; Zhang, Zhi-Xin; Ye, Si-Han; Chen, Yang-Bo; Luo, Wen-Feng; Qian, Peng-Cheng; Ye, Long-Wu researched the compound: Copper(I) tetra(acetonitrile) tetrafluoroborate( cas:15418-29-8 ).Category: ruthenium-catalysts.They published the article 《Copper-Catalyzed Carbocyclization of Silyl Enol Ether Tethered Ynamides for Efficient and Practical Synthesis of 2-Azabicyclo[3.2.0] Compounds》 about this compound( cas:15418-29-8 ) in Chinese Journal of Chemistry. Keywords: azabicyclo compound preparation regioselective diastereoselective; silyl enol ether ynamide carbocyclization copper catalyst. We’ll tell you more about this compound (cas:15418-29-8).
An efficient copper-catalyzed carbocyclization of silyl enol ether tethered ynamides has been developed, allowing rapid and practical construction of diverse 2-azabicyclo[3.2.0] compounds I (PG = Ts, 4-bromobenzenesulfonyl, 4-methoxybenzenesulfonyl; R = C6H5, 4-FC6H4, hexyl, etc.). in generally good to excellent yields with broad substrate scope under mild reaction conditions. Importantly, this protocol not only constitutes a rare example of non-noble metal-catalyzed alkyne carbocyclization, but also represents a rare cyclization on the β-position of π-tethered ynamides. The possibility of asym. carbocyclization via kinetic resolution also emerges.
