Examples of such amino-protecting groups include the formyl group, the trityl group, the phthalimido group, the acetyl group, the trichloroacetyl group, the chloroacetyl, bromoacetyl, and iodoacetyl groups, urethane-type blocking groups such as benzyloxycarbonyl, 9-fluorenylmethoxycarbonyl (“FMOC”),...
Treatment of O2,2′-anhydrouridine with triphenylmethyl chloride in pyridine at 80°C gives mainly the 2′-chlorinated nucleoside 3. Reaction of 2′-chloro-3′-0-trifluoromethane-sulfonyl-5′-0-trityl-2′-deoxyuridine (4) with NaOH led exclusively to the elimination product 5, opening the ...
