The Sonogashira coupling reaction of ethynylferrocene with adenine, uracil, tyrosine and steroid derivatives was studied; with the exception of tyrosine it was proved to be a good route for the attachment of ferrocene to these representative biomolecules. In addition the transformation of alkynyl uracil to furanopyrimidone derivatives was investigated and the formation of the furanopyrimidone ring was confirmed by an X-ray crystallographic analysis carried out on product 16.
研究了二茂铁乙炔与腺嘌呤、尿嘧啶、酪氨酸和类固醇衍生物的 Sonogashira 偶联反应;除酪氨酸外,该反应被证明是二茂铁附着于这些代表性生物大分子的良好途径。此外,还研究了炔基尿嘧啶向呋喃嘧啶酮衍生物的转化,对产物 16 进行的 X 射线晶体分析证实了呋喃嘧啶酮环的形成。
