a reaction that effectively bends rigid oligoproline peptides (see scheme; TBDMS=tert‐butyldimethylsilyl). The stitching is accomplished during macrocyclization enabled by aziridine aldehydes and isocyanides. Molecular modeling studies suggest that electrostatic attraction between the termini of the linear peptide is pivotal for macrocyclization. The macrocycles were studied by circular dichroism with
弯曲但不折断:在有效弯曲刚性寡脯氨酸肽的反应中获得环状低聚脯氨酸(请参阅方案; TBDMS =叔丁基二甲基甲硅烷基)。通过氮丙啶醛和异氰酸酯实现的大环化过程中完成了缝合。分子模型研究表明,线性肽末端之间的静电吸引对于大环化至关重要。通过圆二色性研究了大环,在较大的大环中观察到了聚脯氨酸II结构。
