The synthesis of new chiral seleno-, telluro-, and thio-N-Boc-γ-amino acids is described herein. These new compounds were prepared through a simple and short synthetic route, from the inexpensive and commercially-available amino acid L-glutamic acid. The products, with a highly modular character, were obtained in good to excellent yields, via hydrolysis of chalcogen pyroglutamic derivatives with overall
本文描述了新的手性硒代,碲代和硫代-N - Boc -γ-氨基酸的合成。这些新化合物是通过简单且短的合成路线,由廉价且可商购获得的氨基酸L-谷氨酸制备的。通过硫属元素焦谷氨酸衍生物的水解以及L-谷氨酸立体化学的整体保留,以高至优异的产率获得了具有高度模块化特征的产物。同样,以高收率制备了L-二硒化物-N - Boc -γ-氨基酸。这种新的合成途径代表了制备新的L-硫属元素和L的有效方法具有生物潜力的-二硒化物-γ-氨基酸。
