Reference of cis-4-Aminocyclohexane carboxylic acid. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about The cis-3- and trans-4-aminocyclohexanecarboxylic acids and their esters. Author is Palaima, A.; Poskiene, R.; Karpavicius, K.; Kil’disheva, O. V.; Knunyants, I. L..

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.

Different reactions of this compound(cis-4-Aminocyclohexane carboxylic acid)Reference of cis-4-Aminocyclohexane carboxylic acid require different conditions, so the reaction conditions are very important.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 3-Methyl-1H-pyrrole(SMILESS: CC1=CNC=C1,cas:616-43-3) is researched.Computed Properties of C6Cl2N4. The article 《Direct Synthesis of Bipyrroles Using Phenyliodine Bis(trifluoroacetate) with Bromotrimethylsilane》 in relation to this compound, is published in Organic Letters. Let’s take a look at the latest research on this compound (cas:616-43-3).

Bipyrroles and a biindole are prepared regioselectively by oxidative dimerization of pyrroles or indoles with phenyliodine bis(trifluoroacetate) (PIFA) in the presence of bromotrimethylsilane. 3,4-Disubstituted pyrroles and 4,5,6,7-tetrahydroisoindole undergo dimerization to give 2,2′-bipyrroles (or 4,4′,5,5′,6,6′,7,7′-octahydro-1,1′-biisoindole) in 60-78% yields (with respect to PIFA). 3-Substituted-1H-pyrroles undergo regioselective oxidative dimerization with PIFA and bromotrimethylsilane to give 3,4′-disubstituted-2,2′-bipyrroles as the major products in 52-82% yields along with varying amounts of the 3,3′-disubstituted-2,2′-bipyrroles. 3-Methylindole undergoes oxidative dimerization to give 3,3′-dimethyl-2,2′-biindole in 74% yield in addition to 29% of 2-(3-methyl-1-indolyl)-3-methylindoline. While pyrrole undergoes oxidative dimerization with PIFA and bromotrimethylsilane to give only 2,2′-bipyrrole in 78% yield, 1-phenylpyrrole reacts under similar conditions to give 1,1′-diphenyl-2,3′-bipyrrole in 56% yield.

The article 《Direct Synthesis of Bipyrroles Using Phenyliodine Bis(trifluoroacetate) with Bromotrimethylsilane》 also mentions many details about this compound(616-43-3)Electric Literature of C5H7N, you can pay attention to it, because details determine success or failure
