A 3′-C-hydroxymethyl-branched Locked Nucleic Acid (LNA) monomer 3 was synthesized from diacetone-α-D-glucose taking advantage of a stereoselective Grignard reaction for the introduction of a vinyl group, an aldol/Cannizzarro sequence for introducing the 4′-substituent, oxidative cleavage of the vinyl group using a RuO4-based protocol, Vorbruggen-type nucleobase coupling and finally the ring closure
3'-C-羟甲基支链锁核酸 (LNA) 单体 3 由双丙酮-α-D-葡萄糖合成,利用立体选择性格氏反应引入乙烯基,醛醇/康尼查罗序列用于引入使用基于 RuO4 的协议、Vorbruggen 型核碱基偶联和最终通过醚形成闭环给出双环骨架的 4'-取代基氧化裂解乙烯基。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
