9‐Helix: 4‐Amino(methyl)‐1,3‐thiazole‐5‐carboxylic acids (ATCs) were synthesized as new γ‐amino acid building blocks. The structures of various ATC oligomers were analyzed in solution by CD and NMR spectroscopy and in the solid state by X‐ray crystallography. The ATC sequences adopted a well‐defined 9‐helix structure in the solid state and in aprotic and protic organic solvents as well as in aqueous
9-螺旋:合成了4-氨基(甲基)-1,3-噻唑-5-羧酸(ATC)作为新的γ-氨基酸构件。各种ATC低聚物的结构在溶液中通过CD和NMR光谱分析,在固态下通过X射线晶体学分析。ATC序列在固态,非质子和质子有机溶剂以及水溶液中均采用明确定义的9螺旋结构。
