Direct Alkylation of 1-Azabicyclo[1.1.0]butanes was written by Gianatassio, Ryan;Kadish, Dora. And the article was included in Organic Letters in 2019.COA of Formula: C8H11N This article mentions the following:
The facile synthesis of functionalized azetidines has been an ongoing challenge. Here, we report a general method to directly alkylate 1-azabicyclo[1.1.0]butane (ABB) with organometal reagents in the presence of Cu(OTf)2 to rapidly prepare bis-functionalized azetidines. This method allows for the preparation of azetidines bearing alkyl, allyl, vinyl, and benzyl groups. This catalyst system was extended to aziridines and spirocycles. Several building blocks and drug-like compounds were prepared in rapid fashion and in good yield. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4COA of Formula: C8H11N).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.COA of Formula: C8H11N
