DOI: 10.3184/174751918x15341514233168
Abstract: A practical four-step synthesis of pymetrozine is reported, starting from a green chemical dimethyl carbonate and using the key intermediate methyl (E)-1-(2-oxopropyl)-2-(pyridin-3-ylmethylene)hydrazine-1-carboxylate. The main advantages of the route include inexpensive starting materials, environmental friendliness, short… read more here.
