lic acid (1) was synthesized for potential use in boron neutron capture therapy. Starting from the readily available 3-(bromomethyl)cyclobutanone ketal (4), several synthetic routes to 1 were evaluated. After several unsuccessful attempts with traditional synthetic methods, a novel synthetic strategy to generate the new boronated cyclic amino acid was developed. The tolerance of the hydantoin group
合成了一种新型的硼化氨基环丁烷羧酸(1),可用于硼中子俘获治疗。从容易获得的3-(溴甲基)环丁酮缩酮(4)开始,评估了几种合成1的途径。在用传统的合成方法进行了几次失败的尝试之后,开发了一种新的合成策略来生成新的硼酸化环状氨基酸。在制备烯基化合物7中,乙内酰脲对亚硒酸消除反应条件的耐受性是新策略中的关键步骤。
