Mesoionic pyrido[1,2-a]pyrimidinones: Discovery of dicloromezotiaz as a lepidoptera insecticide acting on nicotinic acetylcholine receptors1,2

A novel class of mesoionic pyrido[1,2-a]pyrimidinones has been discovered with exceptional insecticidal activity controlling a number of insect species. In this communication, we report the part of the optimization program that led to the identification o

A stereoselective process for the preparation of novel phosphonoalkylphosphinates

We have devised both a contiguous and a stepwise strategy for the synthesis of the pyridylaminomethane-based class of phosphonoalkylphosphinates (PAPs) that form via the intermediacy of the phosphonoethoxyaminomethane XIa. The PAPs result from condensation of picolines and phosphonoacetals in high chemoselective yield. Following reduction of aminopyridine IIIb, the unprecedented Pt(0)-catalyzed epimerization of the chelated amidine [(hydroxy)methylphosphinyl]-[(3-methyl-2-piperidinyl-idene)amino]methylphosphonic acid (IIIa) yielded a single racemic pair of PAPs (IIIc). The epimerization was found to occur more slowly than amidine formation itself.
