with a hemiacetal linker between the C2′ and the C4′-positions was isolated and found to be a suitable substrate for making a conformationally restricted double-headed nucleoside. This contains two uracil nucleobases organized on a bicyclic skeleton and is locked in an N-type conformation.
使用不同的RCM方法制备碳环LNA模拟的尝试失败。然而,分离出在C2'和C4'-位置之间具有半缩醛连接基的化合物,发现该化合物是制备构象受限的双头核苷的合适底物。它包含组织在双环骨架上的两个尿嘧啶核碱基,并锁定在N型构象中。
