A cobalt‐catalyzed decarboxylative Negishi coupling reaction of redox‐active aliphatic esters with organozinc reagents was developed. The method enabled efficient alkyl–aryl, alkyl–alkenyl, and alkyl–alkynyl coupling reactions under mild reaction conditions with no external ligand or additive needed. The success of an in situ activation protocol and the facile synthesis of the drug molecule (±)‐preclamol

The antibacterialactivity of various types of imidazolium, pyrrolidinium and piperidinium salts with both propargyl group and alkyl and/or silylalkyl chains of different lengths, are described. Especially, the MIC (μg/ml) of prepared each compound for Escherichia coli and other several bacteria was determined.

monocycles to complex fused polycyclic systems. The reaction is highly regioselective and takes place under symmetry‐breaking conditions. The preparative power of this reaction was demonstrated in the first total synthesis of morintrifolin B, a benzophenone metabolite isolated from the small tree Morinda citrifolia L. A DFT study of the reaction was performed with full agreement between calculated values and
