derivatives with dimedone (or cyclohexane-1,3-dione) and triethyl orthoacetate (or triethyl orthopropionate) gave derivatives of 7-(1,3-dioxocyclohex-2-ylidene)-7,8-dihydropyrido[2,3-d]pyrimidine. These heterocyclic compounds containing the enamino ketone fragment can form boron chelates under the action of butoxy(diphenyl)borane.
5-乙酰-4-氨基嘧啶衍生物与二甲酮(或环己烷-1,3-二酮)和原乙酸三乙酯(或原丙酸三乙酯)的三组分缩合得到7-(1,3-二氧环己-2-亚基)衍生物-7,8-二氢吡啶并[2,3-d]嘧啶。这些含有烯氨基酮片段的杂环化合物在丁氧基(二苯基)硼烷的作用下可以形成硼螯合物。
