(R,R,R)-γ-Amino acids with side chains in the
2-, 3-, and 4-positions, prepared by addition of acyloxazolidinones to a
nitroolefin and hydrogenation, have been coupled to γ- tetra-, and
γ-hexapeptides which are shown to form (M)-2.614
helices in the crystal state and in MeOH solution.
(R,R,R)-δ-氨基酸的侧链位于 2-、3-和 4-位,是通过将酰基噁唑烷酮与硝基烯烃加成并氢化而制备的,已被δ-四肽和δ-六肽偶联,这些δ-四肽和δ-六肽在晶体状态和 MeOH 溶液中形成了 (M)-2.614 螺旋。
