A facile one-step condensation of the cyclopentenyl a-tosylate 2c with the alkali metal salts of 6-chloropurine and uracil, afforded the protected carbocycl% nucleosides 5a and 8, respectively, which were converted to neplanocin A (6) and cyclopentenyl uracil (r by established methods.
2',3'-Unsaturated nucleosides have been prepared in excellent yields under mild conditions by the condensation of acetylated glycals with purine or pyrimidine derivatives in the presence of trityl perchlorate. The synthesis of ((w-and P-hex-Z enopyranosyl-4-ulose)theophylline nucleosides labelled at
