Reactions of 3-(polyfluoroacyl)chromones and their hetero analogues with a number of 1,3-NCN-dinucleophiles, such as amidines or guanidines, were studied in detail, and preparative access to a set of diverse 5-salicyloyl-4-(polyfluoroalkyl)pyrimidines was elaborated. These compounds appear to be a suitable starting substrates for the synthesis of 4-(polyfluoroalkyl)pyrimidine-5-carboxylic acids or
3-(polyfluoroacyl)chromones及其杂类类似物与许多1,3- NCN -dinucleophiles(例如am或胍)的反应进行了详细研究,并制备了一系列不同的5-salicyloyl-4-(精心设计了多氟烷基)嘧啶。这些化合物似乎是用于合成在5-位含有苯并呋喃-3-基取代基的4-(多氟烷基)嘧啶-5-羧酸或嘧啶的合适的起始底物。 色酮-硫代色酮-氟-嘧啶核环化-区域选择性-杂环
