✦ Synopsis

1, 1, 3, 3-Tetraisopmpyl-3-(2-(triphenylmcthoxy)ethoxy)disiloxane-l-yl (TES) group was designed for solid-phase RNA synthesis as a 5'-O-protecting group, which can be combined with the tetrahydropyranyl group, a 2'-hydroxyl protecting group. The TES group can be selectively introduced to the 5'-hydroxy group ofnucleosides and can be easily removed by 0.1M tetrabutyl~amonium fluoride or 0.01M hydrochloric acid.
