A direct CO2-fixation methodology couples structurally diverse iminophosphoranes with various nucleophiles to synthesize ureas, carbamates, thiocarbamates, and amides, and is amenable for 11C radiolabeling. This methodology is practical, as demonstrated by the synthesis of >35 products and isolation of the molecular imaging radiopharmaceuticals [11C]URB694 and [11C]glibenclamide.
直接的CO 2固定方法将结构多样的亚氨基正膦与各种亲核试剂偶合,以合成尿素,氨基甲酸酯,硫代氨基甲酸酯和酰胺,适用于11 C放射性标记。如> 35种产品的合成和分子成像放射性药物[ 11 C] URB694和[ 11 C] glibenclamide的分离所证明,该方法是实用的。
