Convenient and efficient methods of the synthesis of N6- and N4-substituted derivatives of adenine and cytosine and their 2′-deoxyribosides were developed. The reactions of either unprotected nucleobases (adenine, cytosine) or unprotected 2′-deoxyribosides with aryl or alkyl aldehydes give corresponding Schiff bases that can be reduced to the target title compounds with high overall yields. In the
