Conjugate additions of carbon nucleophiles to chromone derivatives towards nitrogen heterocycles. In Research Day. Aveirohttp://hdl.handle.net/10198/14521Conjugate additions of nitromethane to the extended π- system of chromone derivatives afforded the 1,6-conjugate addition products, together with structure complex oxygen heterocycles through tandem processes. Further functionalization of targeted adducts allowed the preparation of biological relevant nitrogen heterocycles such as styrylpyrrolidines, as well as pyrazole and bis-pyrazole derivatives.engConjugate additions of carbon nucleophiles to chromone derivatives towards nitrogen heterocyclesconference poster
