A novel class of N-Fmoc-protected amino alkyl thiocyanates/selenocyanates has been prepared by thiocyanation/selenocyanation of the corresponding alkyl iodides. These thiocyanates/selenocyanates undergo a facile [2+3]-cycloaddition reaction with sodium azide to afford novel N-Fmoc amino alkyl S/Se-linked tetrazoles. amino acid derivatives - thiocyanates - selenocyanates - [2+3] cycloaddition - S/Se-linked
通过相应烷基碘的硫氰化/硒氰化制备了新型的N -Fmoc保护的氨基烷基硫氰酸酯/硒氰酸酯。这些硫氰酸盐/硒代氰酸盐与叠氮化钠进行简单的[2 + 3]-环加成反应,得到新颖的N- Fmoc氨基烷基S / Se-连接的四唑。 氨基酸衍生物-硫氰酸酯-硒氰酸酯-[2 + 3]环加成-S / Se相连的四唑
