Cyclopropane side-chained β2,2-aminoxy oligopeptides were synthesized and conformationally studied. β N–O turn in solution and β N–O helix in the solid state was characterized by 1H NMR, 2D NOESY and FT-IR as well as X-ray crystallography studies. Almost no changes has been observed with the disturbance at α carbon bond angle compared with dimethyl substituted one. This study provided the opportunity
合成并构象了环丙烷侧链β2,2-氨基氧寡肽。通过1 H NMR,2D NOESY和FT-IR以及X射线晶体学研究对溶液中的βN–O转变和固态βN –O螺旋进行了表征。与二甲基取代的α相比,在α碳键角处的扰动几乎没有观察到变化。这项研究为以更精细的方式设计生物活性拟肽提供了机会。
