The pivotal intermediate(E)-methyl-2-[2-(bromomethyl) phenyl]-2-(methoxyimino)acetate of trifoxystrobin was synthesized from 2-methylacetophenone via a series of reactions including alkaline oxidation with potassium permanganate in the presence of the phase-transfer catalyst,esterification with methanol, oximation with methoxyamine hydrochloride,bromination with Nbromosuccinimide(NBS). The structure was characterized by means of melting point and1 HNMR.Under the optimized reaction conditions,the total yield...
