New hydrolysis conditions for β-aminosulfamic acids produced from the opening of a cyclic sulfamidate with a variety of primary or secondary amines have been developed. This new hydrolysis method allowed us to use at most two equivalents of amine nucleophiles furnishing 2,3-diaminopropanoate derivatives in good to excellent yields.
已经开发了由与各种伯或仲胺的环状氨基磺酸酯的开环产生的β-氨基氨基磺酸的新的水解条件。这种新的水解方法使我们能够使用最多两个当量的胺亲核试剂,以良好或极好的收率得到2,3-二氨基丙酸酯衍生物。
