A highly facile and efficient one-step synthesis of N 6-adenosine and N 6-2'- deoxyadenosine derivatives has been developed. Treatment of inosine or 2'-deoxyinosine, without protection of sugar hydroxyl groups, with alkyl or arylamines, in the presence of BOP and DIPEA in DMF, led to the formation of N 6-adenosine and N 6-2'-deoxyadenosine derivatives in good to excellent yields. Carcinogenic polyaromatic hydrocarbon (PAH) N 6 ...
