Oxidation of 3-amino-2-trifluoromethylquinazolin-4(3H)-one 6 with lead tetraacetate in dichloromethane gives the title 3-acetoxyamino derivative 7 which is isolable at room temperature and considerably more stable than the corresponding 2-alkyl substituted analogues. Compound 7 aziridinates alkenes in yields which are consistently higher than those from the 2-alkyl substituted analogues. Aziridinations
用四乙酸铅在二氯甲烷中氧化3-氨基-2-三氟甲基喹唑啉-4(3H)-一6,得到标题3-乙酰氧基氨基衍生物7,其在室温下是可分离的,并且比相应的2-烷基取代的类似物更稳定。化合物7使叠氮基氮杂环丁烷烯的产率始终高于2-烷基取代的类似物的产率。已经研究了使用在喹唑啉酮环的2-位上带有其他吸电子基团的3-乙酰氧基氨基喹唑啉酮进行的叠氮化。
