J. Wachtmeister et al., SYNTHESIS OF 2',3'-DIDEOXYCYCLO-2'-PENTENYL-3'-C-HYDROXYMETHYL CARBOCYCLIC NUCLEOSIDE ANALOGS AS POTENTIAL ANTIVIRAL AGENTS, Tetrahedron, 51(7), 1995, pp. 2029-2038
The synthesis of optically pure unsaturated carbocyclic nucleoside ana
logues is described. is(t-butyldiphenylsilyloxymethyl)-2-cyclopenten-1
R and 1S-ol were coupled with 6-chloropurine and 2-amino-6-chloropurin
e respectively, using a modified Mitsunobu reaction. The products were
reacted further using standard procedures to give compounds 12, 14, 1
6 and 18 which were tested for anti-HIV activity.
