Linker phosphoramidite reagents containing a protected nucleoside with a cleavable 3%-ester linkage to either succinic acid, diglycolic acid, or hydroquinone-O,O%-diacetic acid (Q-Linker) allow the 3%-terminal nucleoside of an oligonucleotide sequence to be attached to underivatized 'Universal' amin
Oligoribonucleotides, six to fifteen units long, were synthesized on a controlled pore glass support using ribonucleoside 3'-0-phosphoramidite reagents. Average coupling yieids of up to 98% were obtained with dirsopropylamrnophosphoramidite derivatives. In light of the increasing interest in the ro
