USE OF 2-(2-PYRIDYL)ETHYL GROUP AS A NEW PROTECTING GROUP OF INTERNUCLEOTIDIC PHOSPHATES IN OLIGONUCLEOTIDE SYNTHESIS
2-(2-Pyridyl)ethyl group is used as a highly selective protecting group of internucleotidic phosphates that is removable under mild conditions by treatment with CH3I in CH3CN without a side reaction such as N-alkylation.
