Note:The synthesis of 5’-monomethoxytrityl-2'-tert-butyldimethylsilyl-3'-levulinylribonucleosides of the four common bases as well as their 2',3' isomeric derivatives was accomplished. These units are suitable for block condensations via the phosphite procedure as demonstrated in the preparation,in good yield, of a hexadecauridylic acid. A novel solid phase synthesis of ribonucleotides featuring the use of the phosphite procedure, along with a derivatized silica gel polymer, was fully investigated. The efficiency of the method is exemplified in the stepwise assembly of a nonadecamer corresponding to the dihydrouridine loop of t-RNAfMet. Several mild reagents capable of hydrolyzing nucleotides from the polymer were introduced. In addition, a...
