Facile synthesis of 2'-deoxyisoguanosine and related 2',3'-dideoxyribonucleosides
Seela,Gabler
, p. 622 - 630 (1994)
The 2'-deoxyisoguanosine (1) was synthesized by a two-step procedure from 2'-deoxyguanosine (5). Amination of silylated 2'-deoxyguanosine yielded 2-amino-2'-deoxyadenosine (6) which was subjected to selective deamination of the 2-NH2 group resu
