A reaction of 3-acetyl-4-amino-5,5,5-trifluoropent-3-en-2-one diphenylboron chelate and ammonia or primary amines affords 4-amino- or 4-alkylamino-3-trifluoroacetimidoylpent-3-en-2-ones, new reagents which can be used for the synthesis of pyrimidines with trifluoromethyl group.
3-乙酰基-4-氨基-5,5,5-三氟戊-3-烯-2-酮二苯基硼配合物与氨或伯胺反应,得到4-氨基或4-烷基氨基-3-三氟乙脒基戊-3-烯-2-酮,这些新试剂可用于三氟甲基嘧啶的合成。
