1-[(2-trimethylsilyl)ethoxy]ethyl (SEE) group, readily obtainable from an alcohol and 2-(trimethylsilyl)ethyl vinyl ether in the presence of a catalytic amount of PPTS, has been developed for the protection of hydroxyl groups. Its deprotection can be achieved under virtually neutral conditions with the use of a fluoride ion source, thus allowing for effective protection of hydroxyl groups of compounds that
已经开发出高度通用的1-[((2-三甲基甲硅烷基)乙氧基]乙基(SEE),可在催化量的PPTS存在下从醇和2-(三甲基甲硅烷基)乙基乙烯基醚容易地获得,已被保护用于保护羟基。可以使用氟离子源在几乎中性的条件下实现脱保护,因此可以有效保护含有酸和/或碱敏感官能团的化合物的羟基。
