synthesis, and conformational studies of a novel hybrid foldamer that adopts a definite compact, three-dimensional structure determined by a combined effect of the special conformational properties of the foldamer constituents. The striking feature of this de novo designed foldamer is its ability to display periodic γ-turn conformations stabilized by intramolecular hydrogen bonds. Conformational investigations
本说明描述了新型混合型折叠式折叠器的设计,合成和构象研究,该折叠式折叠器采用了确定的紧凑的三维结构,该结构由折叠式折叠器成分的特殊构象特性共同决定。这种从头设计的折叠剂的显着特征是它能够显示出通过分子内氢键稳定的周期性γ转构象的能力。通过单晶X射线研究,溶液态NMR和从头算MO理论在HF / 6-31G *水平进行的构象研究强有力地支持了二肽和四肽折叠子中γ转角基序的普遍存在。大概是通过分叉的氢键稳定在固态和溶液态。
