摘要
An efficient synthesis of protected ribonucleosides useful for phosphoramidite RNA synthesis is described. Di-t-butylsilylene group was employed for simultaneous protection of 3'- and 5'-hydroxyl functions of nucleoside, Subsequent silylation of free 2'-OH group followed by introduction of suitable protection on the base moiety. removal of cyclic silyl protection and tritylation of 5'-OH gave target compounds in 60-66%. overall yield.
