The first iridium-catalyzed three-component coupling reaction of carbon dioxide, amines, and sulfoxonium ylides has been developed, providing an efficient and straightforward method for the construction of a range of structurally diverse O-β-oxoalkyl carbamates in moderate to excellent yields. This novel protocol features the use of readily available substrates, wide substrate scope, and good functional
已经开发出第一催化铱,二氧化碳,胺和亚硫酸sulf鎓烷基化物的三组分偶联反应,提供了一种有效且直接的方法来以中等至优异的产率构建一系列结构多样的O -β-氧代烷基氨基甲酸酯。这种新颖的协议的特点是易于使用的底物,广泛的底物范围和良好的官能团耐受性。此外,无光气策略已成功应用于潜在的抗肿瘤药物的合成。
