We report a selective ruthenium catalyzed reduction of tertiary amides on the side chain of Fmoc-Gln-OtBu derivatives, leading to innovative unnatural α,β or γ-amino acids functionalized with tertiary amines. Rapid and scalable, this process allowed us to build a library of basic unnatural amino acids at the gram-scale and directly usable for liquid- or solid-phase peptide synthesis. The diversity
我们报道了选择性钌催化的Fmoc-Gln-O t Bu衍生物侧链上的叔酰胺还原,导致创新的用叔胺官能化的非天然α,β或γ-氨基酸。快速且可扩展,该过程使我们能够建立克级的基本非天然氨基酸文库,并可直接用于液相或固相肽合成。可用叔胺的多样性使我们能够调节所得氨基酸的物理化学性质,例如碱性或疏水性。
