5′-O-Acryloyl-5-fluorouridine was prepared by use of p-methoxybenzyl (PMB) group as an N3-imide protecting group of 5-fluorouridine. PMB group was introduced chemoselectively by use of N,N-diisopropylethylamine or DBU as a base. A new deprotection method was developed by means of AlCl3–anisole system at room temperature.
5′-O-Acryloyl-5-fluorouridine 是用对甲氧基苄基 (PMB) 作为 5-fluorouridine 的 N3-imide 保护基来制备的。通过使用
N,N-二异丙基乙胺或
DBU 作为碱来
化学选择性地引入 PMB 基团。在室温下,通过
AlCl3-anisole 系统开发了一种新的脱保护方法。
