Synthesis and structural characterization of new cu(I) complexes with the antithyroid drug 6-n-propyl-thiouracil. Study of the cu(I)-catalyzed intermolecular cycloaddition of iodonium ylides toward benzo[b]furans with pharmaceutical implementations
(2012)The reaction of copper(I) iodide with 6-n-propylthiouracil (ptu) in the presence or absence of the triphenylphosphine (tpp) or tri(p-tolyl)phosphine (tptp) in a 1:1:2 molar ratio forms the mixed ligand Cu(I) complex with ...

Three-step synthesis of ethyl canthinone-3-carboxylates from ethyl 4-bromo-6-methoxy-1,5-naphthyridine-3-carboxylate via a Pd-catalyzed Suzuki-Miyaura coupling and a Cu-catalyzed amidation reaction
(2011)Ethyl canthin-6-one-1-carboxylate (1b) and nine analogues 1c-k were prepared from readily prepared ethyl 4-bromo-6-methoxy-1,5-naphthyridine-3- carboxylate (2b) via a three-step non-classical approach that focused on ...
