Abstract
Backbone-modified DNA analogs were synthesized in good yields by the boranophosphotriester method on a solid support. The oligodeoxyribonucleoside boranophosphates, protected with 2-(azidomethyl)benzoyl groups for nucleobases, were converted into DNA and its backbone-modified analogs via the corresponding H-phosphonate intermediates. A new protecting group for the O6 position of 2′-deoxyguanosine, 4-azidobenzyl (ABn) group, was also developed. The ABn group can be quickly removed by treatment with MePPh2 and H2O in the presence of 2-mercaptoethanol.
