An efficient and concise total synthesis of naturally occurring pyranochalcones was achieved from readily available 2,4-dihydroxyacetophenone and 2,4-dihydroxy-6-methoxyacetophenone. The key steps in the synthetic strategy were ethylenediamine diacetate-catalyzed benzopyran formation and aldol reactions.

Novel polymer based photoluminescent nanoparticles were fabricated by ultra-sound induced emulsion polymerization and applied to bioimaging of human breast cancer SK-BR-3 cells after ethylenediamine treatment and conjugation with anti-ErbB2 antibody.

The catalyst-free multicomponent reaction of 1,2-diaminobenzene, dialkyl acetylenedicarboxylates, and ethyl bromopyruvate forms pyrrolo[1,2-a]quinoxaline derivatives in good yields. Ethylenediamine also reacts under similar conditions to produce new pyrrolo[1,2-a]pyrazine derivatives.

Three naphtol derivativesweresynthesized using several strategies; in first stage, was synthetized the compound 4(1-[(2-Amino-ethylamino)-phenyl-methyl]-naphthalen-2-ol) using the three-component system (β-naphtol, benzaldehyde and ethylenediamine).The secondstage involves the synthesis of1-{[2-Hex-1-ynyl-phenyl-amino)-ethylamino]-phenyl-methyl}-naphtalen2-ol (6) by the reaction of 4 with 1-hex...

Gold nanoparticles have been used for analytical and biomedical purposes for many years. In fact, the labeling of targeting molecules with nanoparticles has revolutionized the visualization of cellular or tissue components by electron microscopy. We report in this study the derivatization of tiopronin-protected nanoparticles with ethylenediamine and poly(ethylene glycol) bis(3-aminopropyl) term...

Differential pulse anodic stripping voltammetric study of zinc-ethylenediamine complex has been investigated using thin mercury film coated glassy carbon electrode at 30°C. The overall work was carried out at constant ionic strength (I = 0.20 mol dm -3 ) and pH (9.10±0.10). The electrode processes were found to be reversible and diffusion controlled. The results revealed that zinc forms three (...

The title compound, poly[dizinc(II)-mu-ethylenediamine-di-mu-(hydrogen phosphito)], beta-[H(2)N(CH(2))(2)NH(2)](0.5)[ZnHPO(3)] or [Zn(2)(HPO(3))(2)(C(2)H(8)N(2))](n), is a hybrid organic/inorganic solid built up from ethylenediamine molecules (which lie about inversion centres), Zn(2+) cations (coordinated by three O atoms and one N atom) and HPO(3)(2-) hydrogen phosphite groups. The organic sp...
