pentafluoropropenyl derivatives of pyrimidine and purine bases have been obtained in good to high yield. The procedure involves the reaction of appropriate lithium derivatives prepared from both electron-rich and electron-poor pyrimidines, with the hexafluoropropene at a low temperature, via an addition−elimination process. Organolithiums of pyrimidine and purine bases give addition−elimination products as
已经以良好至高收率获得了嘧啶和嘌呤碱的各种五氟丙烯基衍生物。该程序涉及通过加成消除法在低温下由富电子和贫电子嘧啶制备的合适的锂衍生物与六氟丙烯反应。嘧啶和嘌呤碱的有机锂以E / Z混合物形式提供加成消除产物,而受保护的肌苷的氨基酰胺锂与六氟丙烯的反应产物则含有痕量的加成产物以及稳定的全氟烯胺。所提出的方法允许快速方便地获得一系列全氟乙烯基核碱基。
