The intramolecular aza-Wittig reaction of (5S)-N-[2-(trisubstituted-phosphoranylidene)aminobenzoyl]-2-pyridone-5-carboxylic acid derivatives chemoselectively gave 5-pyrrolo[2,1-c][1,4]benzodiazepinone derivatives or 5(1H)-pyrrolo[2,1-b]quinazolinone derivatives depending on the substituents.
(5S)-N-[2-(三取代-磷酰)氨基苯甲酰基]-2-吡啶酮-5-羧酸衍生物的分子内氮-维蒂格反应根据取代基的不同,可选择性地生成5-吡咯并[2,1-c][1,4]苯并二氮杂卓酮衍生物或5(1H)-吡咯并[2,1-b]喹唑啉酮衍生物。
