WebRNA deprotection is unique because of the necessity to retain the 2' protecting group during cleavage and base deprotection. 2'-OMe-RNA and 2'-F-RNA, however, are virtually identical to DNA during deprotection. But, if a hybrid oligonucleotide contains even a single RNA linkage (with the exception of a 3'-ribonucleoside linkage), the oligo must ...
WebEven after long reaction times, excess of the reagent, and elevated temperatures, alkylation of the positions 2 and 3 was less than 11%, as confirmed by 13 C NMR spectroscopy (Figure 91). This selectivity is in the same range as for the unsubstituted trityl function. Moreover, the detritylation succeeds 20 times faster. WebDec 18, 2015 · This step is also known as detritylation, or deprotection. Step 2: Coupling.
