Abstract

A process for preparing a trinucleotide phosphoramidite comprising reacting a 3',5'-dihydroxy dinucleoside with a nucleoside 5'-phosphoramidite; oxidizing this trinucleotide phosphite to produce the 3'-hydroxyl trinucleotide; and finally converting the 3'-hydroxy trinucleotide to the 3'-phosphoramidite derivative. Such trinucleotide phosphoramidites provide a convenient route for synthesizing oligonucleotides with randomized codons at specified positions.
