terminal alkynes using 1,3-diiodo-5,5,-dimethylhydantoin and HF-based reagents is disclosed. This approach is used to prepare a fluorinated tamoxifen derivative in two steps from commercially available starting materials. A facile method enabling controlled regioselective double iodofluorination of terminal alkynes is also presented.
公开了使用1,3-二碘-5,5,-二甲基乙内酰脲和基于HF的试剂进行内部和末端炔的区域和立体选择性碘氟化的新方案。该方法用于从市售原料中分两步制备氟化他莫昔芬衍生物。还提出了一种可控制末端炔烃的区域选择性双碘氟化的简便方法。
