Improved synthesis of 2'-deoxyformycin A and studies of its in vitro activity against mouse lymphoma of T-cell origin

7-Amino-3-(2'-deoxy-beta-D-ribofuranosyl)pyrazolo[4,3-d]pyrimidine (2'-deoxyformycin A) was synthesized from formycin A by a sequence consisting of (i) 3',5'-cyclosilylation with 1,3-dichloro-1,1,3,3-tetraisopropyldisiloxane, (ii) 2'-acylation with phenoxythiocarbonyl chlori...
