SYNTHESIS OF MESO-2',3'-DIDEOXY-3'BETA-HYDROXYMETHYL CARBOCYCLIC NUCLEOSIDES AS POTENTIAL ANTIVIRAL DRUGS - UNUSUAL COMPETITIVE 2-O-VERSUS N-1-ALKYLATION OF 3-SUBSTITUTED PYRIMIDINES UNDER MITSUNOBU CONDITIONS

Perkin transactions. I, (11), 1994, pp. 1401-1410
The synthesis of meso-2',3'-dideoxy-3'beta-hydroxymethyl carbocyclic n
ucleosides as potential antiviral drugs via the alkylation of protecte
d purines and pyrimidines with meso-beta,beta'-disubstituted cyclopent
anols under Mitsunobu conditions is described. Chemical evidence for a
n unusual competitive 2-O vs. N-1-alkylation of 3-substituted pyrimidi
nes is presented.
