Abstract

The highly versatile 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 contain acid-and/or base- ...
