Abstract
A series of novel analogs of acyclovir, substituted with an alkyl (methyl, ethyl, n-butyl) or phenyl group at the positions 1′, 4′, and/or 5′, has been obtained in a direct one-pot coupling reaction of guanosine and the respective 1,3-dioxolanes. The new acyclonucleosides were essentially inactive in antiviral (HSV, VV, VSV, HBV) evaluation in vitro.
