A series of cyclic enediyne-containing amino acids with ring sizes varying from 10 to 12 atoms have been prepared starting from propargylglycine and homopropargylglycine. Their reactivity towards Bergman cyclisation under elevated temperatures has been explored. The enediynes displayed marked differences in cyclisation half-lives depending on the olefinic substituent and the ring size. A potential candidate for incorporation into peptides has been identified.
我们以丙炔甘氨酸和均丙炔甘氨酸为起点,制备了一系列环大小从 10 个原子到 12 个原子不等的含烯二炔的环状氨基酸。研究人员探讨了它们在高温下与伯格曼环化反应的活性。根据烯烃取代基和环的大小,这些烯炔类化合物的环化半衰期存在明显差异。已确定了一种可用于肽的潜在候选化合物。
