Ethyl 4,4-difluoro-4-phenoxyacetoacetate was obtained and studied as a precursor to new heterocyclic compounds. 6-Hydroxypyrimidine, 1,3-dihydro-1,5- benzodiazepin-2-one, quinolin-2-one and 6-hydroxypyrazolo[3,4-b]pyridine derivatives containing phenoxydifluoromethyl groups were synthesized. These results make it possible to introduce aryloxydifluoromethyl substituents for the design of biologically
获得 4,4-二氟-4-苯氧基乙酰乙酸乙酯并将其作为新杂环化合物的前体进行研究。合成了含有苯氧基二氟甲基的6-Hydroxypyrimidine、1,3-dihydro-1,5-benzodiazepin-2-one、quinolin-2-one和6-羟基吡唑并[3,4-b]吡啶衍生物。这些结果使得引入芳氧基二氟甲基取代基以设计生物活性杂环成为可能。
