Amino alcohols undergo W(CO)6-catalyzed oxidative carbonylation to the corresponding hydroxyalkylureas without protection of the hydroxyl group. Selected examples of 1,2-, 1,3-, 1,4-, and 1,5-amino alcohols were converted to the ureas in good to excellent yields, with only small amounts of the cyclic carbamates being formed. In contrast, the phosgene derivatives CDI and DMDTC undergo stoichiometric
氨基醇经过W(CO)6催化的氧化羰基化反应生成相应的羟烷基脲,而没有保护羟基。将1,2-,1,2-,1,3-,1,4-和1,5-氨基醇的选定实例以良好至优异的产率转化为脲,仅形成少量的环状氨基甲酸酯。相反,光气衍生物CDI和DMDTC与氨基醇底物进行化学计量反应,从而以可变的选择性提供脲和环状氨基甲酸酯。
