A convenient one-pot synthesis of N-phosphoryl- and N-thiophosphoryl-2-oxo-1,2-azaphospholanes was developed, starting from commercially available or simple-to-prepare phosphorus(III) acid chlorides and (3-bromopropyl)amine hydrobromide. The method is based on the intramolecular Arbuzov reaction of bis-phosphorus(III)-substituted N-(3-bromopropyl)amines generated in turn by double phosphorylation of
的一种方便的一锅合成Ñ -phosphoryl-和Ñ -thiophosphoryl -2-氧代-1,2- azaphospholanes被开发,从可商购的或简单到制备磷(III)酰氯和起始(3-溴丙基)氢溴酸胺。该方法基于双磷(III)取代的N-(3-溴丙基)胺的分子内Arbuzov反应,依次通过(3-溴丙基)胺的双重磷酸化生成,然后氧化或将硫添加到环状磷中(三)种形成。 磷(III)烷基化-闭环-杂环-1,2-氮杂膦酸酯-非对映异构体
