described for the preparation of an oxygen functionalized vinylcopper reagent. Reactions of this reagent with cyclic and acyclic enones give products of 1,4 addition. The labile methoxyisopropyl group was used as an alcohol protecting group for ease of formation and removal. The influence of reaction conditions such as solvents and temperature on the mode of addition and yield is discussed. (S)-1-Iodo-trans-1-octen-3-ol
描述了用于制备氧官能化乙烯基铜试剂的2种方法。该试剂与环状和无环烯酮反应生成 1,4 加成产物。不稳定的甲氧基异丙基用作醇保护基团以易于形成和去除。讨论了溶剂和温度等反应条件对加入方式和收率的影响。(S)-1-Iodo-trans-1-octen-3-ol (16a) 由 (S)-1-octyn-3-ol (17) 制备。将光学纯的碘乙烯基甲醇转化为铜酸盐 2 和 1,4,加入羟基保护的环戊烯酮 14c,得到 (-)-PGE1 (18b)。
