We report a shuttle approach for the Rh-catalyzed anti-Markovnikov hydroiodination of terminal alkynes to vinyl iodides. For aliphatic alkynes, a ligand- and substrate-dependent stereodivergence is observable. The vinyl iodides are engaged in a variety of C−C and C−X bond-forming reactions. The method is used to shorten a synthetic sequence to a cis-fatty acid. Deuterium-labeling and stoichiometric
我们报告了一种用于 Rh 催化的末端炔烃反马尔可夫尼科夫氢碘化为乙烯基碘化物的穿梭方法。对于脂肪族炔烃,可以观察到配体和底物依赖性立体分歧。乙烯基碘化物参与各种 C−C 和 C−X 键形成反应。该方法用于将合成序列缩短为顺式脂肪酸。氘标记和化学计量实验提供了对该机制的深入了解。
