To search for new protoporphyrinogen oxidase (PPO, EC 1.3.3.4) inhibitors with improved bioactivity, a series of novel pyrido[2,3-d]pyrimidine-2,4-dione-benzoxazinone hybrids, 9-13, were designed and synthesized. Several compounds with improved tobacco PP

Efficient one-pot microwave-assisted synthesis of various benzo-[1,4]-oxazinones via Smiles rearrangement is described. Treatment of 2-chloroacetamide, substituted 2-chlorophenols and cesium carbonate in MeO-PEG-OMe (2,000) as solvent afforded the corresp

The electrochemical behavior of o-nitrophenoxyacetophenone, o-nitrophenoxyacetic acid and some related compounds (methyl ester, amide, nitrile) has been investigated in protic media.Controlled potential reductions allow the preparation of 2H-1,4-benzoxazine derivatives from the cyclization of the corresponding phenylhydroxylamines, but the latter can also disproportionate.In some cases, a retrocyclization was observed in warm acidic media, followed by a rearrangement of the parent phenylhydroxylamine. controlled potential electroreductions / 2H-1,4-benzoxazines / cyclic hydroxamic acid / lactam
