CF3SO3SiMe3-catalysed one-to-one exchange of oxathioacetals to carbonyl compounds in the presence of 4-nitrobenzaldehyde is performed efficiently at room temperature, the protocol developed provided selective and effective deprotection of oxathiolanes in the presence of thioacetals.
在4-硝基苯甲醛存在下,以CF3SO3SiMe3为催化剂,可在室温下高效进行氧硫缩醛的一对一交换反应,转化为羰基化合物。该开发的方法提供了在硫缩醛存在下的氧硫缩醛选择性且有效的去保护。
