The synthesis of new chiral non-natural seleno-, thio-, and telluro-peptides is described herein. These new compounds were prepared through simple and brief synthetic route, from inexpensive and commercially available amino acids. The products, possessing a highly modular character, were obtained in good to excellent yields (50–96%), via ring opening of aziridines with chalcogenolate anions, generated
本文描述了新的手性非天然硒代,硫代和碲代肽的合成。这些新化合物是通过简单,简短的合成路线,由廉价且可商购的氨基酸制备的。通过使用碘化铟(I)作为还原剂生成的硫氰酸ogen酯与硫属ogen酸酯阴离子进行开环反应,可以得到具有良好模块化特性的产品,具有良好至极好的收率(50-96%)。
