- Electroepoxidation of natural and synthetic alkenes mediated by sodium bromidePublication . Inês, Massuquinini; Mendonça, António; Esteves, Ana P.; Mendonça, Dina; Medeiros, Maria J.Electroepoxidation of synthetic alkenes (styrene, trans-stilbene and trans-b-methylstyrene) and of some natural terpenes (limonene, terpinolene, geraniol, a-terpinene, g-terpinene and a-terpineol) mediated by sodium bromide was performed in MeCN:H2O (4:1) at platinum electrodes. The indirect electrochemical oxidation of the olefins led to the corresponding epoxides in yields ranging from 23% to 79%.
- Kolbe Electrosynthesis of 1,2-Di(bicyclo[2.2.1]heptan-2-yl)ethane and 1,2-DiphenylethanePublication . Mendonça, António; Inês, Massuquinini; Esteves, Ana P.; Mendonça, Dina; Medeiros, Maria J.Kolbe electrosynthesis, at low current densities, of 1,2-diphenylethane and 1,2-di(bicyclo[2.2.1]heptan-2-yl)ethane with 77 and 72% yields, respectively, is described.
- Synthesis and characterization of novel fluorescent N-glycoconjugatesPublication . Esteves, Ana P.; Rodrigues, Lígia; Silva, Marília Elisabete Tavares Ferreira; Gupta, Sanjay; Campos, Ana Maria Ferreira Oliveira; Machalický, Oldřich; Mendonça, AntónioNovel fluorescent N-glycoconjugates containing D-glucose, glycine and coumarin or naphthalenetriazole derivatives were prepared by peptide synthesis type methods. The fluorescence properties (spectra, quantum yields) of the compounds were evaluated.
