Zusammenfassung:In some embodiments, the present disclosure relates to new phosphoramidite compositions, that have Silyl-containing carbonate or thiocarbonate or ether as 5'-hydroxyl protecting groups useful of the synthesis of DNA, and in particular for the synthesis of long sequences of DNA (e.g., >50 mer). In some embodiments, there are provided methods for simultaneous oxidation of the internucleoside phosphate triester linkages and removal of the 5'-hydroxyl-protecting group, making this process a new 2-step DNA synthesis, that involves the use of peroxyanions in combination with fluoride anions.
