Detritylation reagent
WebThe mixing is carried out in the fluid lines of the synthesis instrument as the reagents are delivered to the solid support. The product is the solid-support-linked nucleoside with an acetylated 5'-OH (pyridine maintains a … 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.
