The synthesis of new ansa1-N45-ethylene cytidines such as 3-ß-D-ribofuranosyl-3,5,6,7-tetrahydro-2H-pyrrolo[2,3-d]pyrimidin-2-one is described and the problems connected with the ring closure to the desired tetrahydro-2H-pyrrolo[2,3-d]pyrimidine base discussed. The lack of biological activities of the new ansa1− cytidines is furthermore commented on.
描述了新的 ansa1-N45-乙烯胞苷如 3-ß-D-ribofuranosyl-3,5,6,7-tetrahydro-2H-pyrrolo[2,3-d]pyrimidin-2-one 的合成及存在的问题与所讨论的所需四氢-2H-吡咯并[2,3-d]嘧啶碱的闭环连接。此外还评论了新的 ansa1-胞苷缺乏生物活性。
