Palaima, A.; Poskiene, R.; Karpavicius, K.; Kil’disheva, O. V.; Knunyants, I. L. published an article about the compound: cis-4-Aminocyclohexane carboxylic acid( cas:3685-23-2,SMILESS:N[C@H]1CC[C@H](CC1)C(O)=O ).COA of Formula: C7H13NO2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:3685-23-2) through the article.
Mixtures of cis- and trans-3-(I) and 4-aminocyclohexanecarboxylic acid (II) were obtained by hydrogenation of the corresponding aminobenzoic acids. Trans-II and cis-I were obtained in 85 and 83% yield, resp., by separation of the mixture on a KU-2 cation exchanger. Cis-II was isomerized to 90% trans-II in the presence of 2% NaOH and Ni/Re catalyst. The Et and Me esters of the title compounds were also obtained.
There are many compounds similar to this compound(3685-23-2)COA of Formula: C7H13NO2. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
