Abstract
Deoxyadenosine has been converted to 6.15N deoxyadenosine, which in turn has been transformed to 1-15N deoxyadenosine. Each of these 15N derivatives was then incorporated into the hexanucleoside pentaphosphate d(CGTACG) via a phosphoramidite procedure. The monomers and die hexamers were characterized by 1H and 15N nmr.
