Hudec, Jozef published the artcileContent of Phenolic Compounds and Free Polyamines in Black Chokeberry (Aronia melanocarpa) after Application of Polyamine Biosynthesis Regulators, Product Details of C3H12Cl2N2, the publication is Journal of Agricultural and Food Chemistry (2006), 54(10), 3625-3628, database is CAplus and MEDLINE.

The total contents of anthocyanins, flavonoids, and phenolics in 60 samples of black chokeberries (Aronia melanocarpa), after treating with catabolites of polyamine biosynthesis (KPAb) and ornithine decarboxylase inhibitor, were analyzed spectrophotometrically, and quercetin and free polyamine contents were analyzed by RP-HPLC with UV detection. The average total contents of the individual substances and phenolic subgroups in control berries were as follows (mg·kg^-1): anthocyanines, 6408; flavonoids, 664; phenolics, 37 600; quercetin, 349. KPAb decreased total contents of anthocyanines and phenolics only slightly but significantly increased the content of flavonoids. This caused an important change in the abundance of flavonoids in the pigment complex. The absolute content of quercetin was increased, but its ratio to flavonoids content was decreased. Ornithine decarboxylase inhibitor had a markedly different effect as it significantly increased total content of anthocyanins and total phenolics, inhibited the total content of free polyamines, and stimulated the processes of saccharides transformation to phenolic pigments.

Mendes, Sofia R. O. published the artcileVibrational and conformational studies of 1,3-diaminopropane and its N-deuterated and N-ionized derivatives, COA of Formula: C3H12Cl2N2, the publication is New Journal of Chemistry (2017), 41(18), 10132-10147, database is CAplus.

A vibrational and conformational anal. of the linear alkylpolyamine 1,3-diaminopropane (1,3-dap) is reported, using vibrational spectroscopy (Raman, Fourier Transform IR (FTIR) and inelastic neutron scattering (INS)) coupled to theor. approaches at the D. Functional Theory (DFT) level. The quantum mech. calculations were carried out using the mPW1PW functional and the 6-31G* basis set, for the isolated mol., the condensed phase, and solutions in both water and carbon tetrachloride. The most stable geometries were calculated to be GGG’G and TG’GG’ for the gaseous phase and the CCl₄ solution, and TTTT, TGTT and TTTG for the condensed phase and the aqueous solution Since the relative populations obtained for the different 1,3-dap conformers were very similar, the corresponding exptl. spectra reflect the presence of a mixture of species. The vibrational data obtained for 1,3-dap in its pure form – unprotonated, totally protonated (N-ionized) and N-deuterated – as well as for its aqueous and CCl₄ solutions, were assigned in the light of the theor. results presently obtained and exptl. data previously gathered for similar compounds

Tomazin, Ursa published the artcileSynthesis of polyenaminones by acid-catalyzed amino-enaminone ‘click’ polymerization, COA of Formula: C3H12Cl2N2, the publication is European Polymer Journal (2018), 603-616, database is CAplus.

A mild amino-enaminone ‘click’ polymerization method for the preparation of polyenaminones by transamination of α,α’-bis-enaminocyclopentanones with diamines was developed. A series of 12 representative polymers were synthesized by acid-catalyzed transamination of two bis-enaminones with six primary 1,2-, 1,3-, and 1,4-diamines. The method allows for combinatorial preparation of structurally diverse polyenaminones from easily available diamines and bis-enaminones. The reaction mechanism was studied by NMR and MS. It involves formation of open-chain and cyclic oligomers, which then undergo a step-wise polymerization to furnish the title polymers with high average mol. weight (M_w > 5.0 × 10⁴ Da) and with spherical and porous microstructure. The obtained polymers were insoluble in most organic solvents, stable in diluted acids and bases, while degradable in concentrated hydrochloric acid at room temperature They were thermally stable up to 200 °C and exhibited film-forming and UV-vis-shielding properties.

Verma, Sanjeev K. published the artcileImidazole-Catalyzed Monoacylation of Symmetrical Diamines, Computed Properties of 10517-44-9, the publication is Organic Letters (2010), 12(19), 4232-4235, database is CAplus and MEDLINE.

An imidazole-catalyzed protocol for monoacylation of sym. diamines has been developed. The protocol gave selective monoacylation of aliphatic (cyclic and acyclic) primary and secondary diamines. In the reaction, imidazole acts as both catalyst and a leaving group. Different monoacylated piperazines and other diamines were synthesized at room temperature in an ethanol/water solvent system.
