Abstract: Here, we investigated the uptake, transport, and subcellular distribution of the pesticides pymetrozine and spirotetramat, and spirotetramat metabolites B-enol, B-glu, B-mono, and B-keto, under hydroponic conditions. Spirotetramat and pymetrozine exhibited high bioconcentrations in lettuce roots,… read more here.

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.
