Alkylation of 2-Pyridinones: Synthesis of Novel Acyclonucleosides. — Acyclohaving 2-pyridinones as nitrogen base are synthesized by alkylation of
44- 231 -N-nucleosides
pyridinone (I) with alkyl compounds like (II). In most cases alkylation occurs both on
the nitrogen atom and on the oxygen atom. Dioxolane derivative (VIII) is obtained as
a sole product by reaction of (I) with chiral dioxolane (VII). The deprotected products
can be further transformed into their tosylates and azido analogues. — (EL-ESSAWY,
