followed by C–O and C–N forming reactions, is presented. A variety of N-aryl-1,4-benzoxazin-3-ones were efficiently synthesized in a one-pot consecutive manner under microwave conditions. A biomass-based, metal- and ligand-free assembly of N-aryl-1,4-benzoxazin-3-ones from methyl 3-dehydroshikimate (3-MHDS), involving aliphatic to aromatic transformation followed by C–O and C–N forming reactions, is presented
摘要 基于生物质的,无金属和无配体的N-芳基-1,4-苯并恶嗪-3-酮从3-脱氢shi草酸甲酯(3-MHDS)的组装,涉及脂肪族到芳香族的转化,然后是C-O和C-给出了N形成反应。在微波条件下以一锅法连续有效地合成了多种N-芳基-1,4-苯并恶嗪-3-酮。 基于生物质的,无金属和无配体的N-芳基-1,4-苯并恶嗪-3-酮从3-脱氢shi草酸甲酯(3-MHDS)的组装,涉及脂肪族到芳香族的转化,然后是C-O和C-给出了N形成反应。在微波条件下以一锅法连续有效地合成了多种N-芳基-1,4-苯并恶嗪-3-酮。
