strategy for the synthesis of unsymmetrical ureas, carbamates, thiocarbamates, and anilides was developed with methyl pyruvate oxime as the carbonyl synthon. The intrinsic reactivity of the reagent enabled consecutive disubstitution involving direct amidation and one-pot deoximative substitution with various nucleophiles. The utility of the method was demonstrated with the synthesis of bioactive molecules
以丙酮酸甲酯肟为羰基合成子,开发了合成不对称脲、氨基甲酸酯、硫代氨基甲酸酯和苯胺的新策略。该试剂的固有反应性使得能够进行连续的取代,包括直接酰胺化和用各种亲核试剂进行一锅脱肟取代。该方法的实用性通过生物活性分子的合成得到了证明。
