ABSTRACT:
Conformationally locked 4',6'-cyclopropane-fused carbocyclic nucleoside analogues. The compounds are prepared by condensing a cyclopropane-fused carbocyclic allylic alcohol with substituted purine or pyrimidine bases. The condensation products are then modified to produce the adenosine, guanosine, cytidine, thymidine and uracil nucleoside analogues. The compounds are therapeutically useful as antimetabolites, or in the preparation of anti-metabolic agents.
