Mesoionic pyrido[1,2-α]pyrimidinone derivatives containing a neonicotinoidmoiety were designed, synthesized, and evaluated for their insecticidalactivity. Some of the title compounds showed remarkable insecticidal properties against Aphis craccivora. Compound I13 exhibited satisfactory insecticidalactivity against A. craccivora. Meanwhile, label-free proteomics analysis of compound I13 treatment

A protocol for the hydrocarboxylation of disubstituted alkenes and terminal alkynes providing access to different secondary carboxylicacids and malonic acid derivatives has been developed. This methodology relies on an initial hydroboration using 9-BBN followed by carboxylation with carbondioxide in the presence of a coppercatalyst and the additive, cesium fluoride. Different cyclohexene, styrene
