Abstract

Solid-liquid PTC without added organic solvent promotes alkylation of purine derivatives leading in particular to an efficient synthesis of the antiviral DHPA. The location of the substituent on the ring was determined by analysis of coupling interactions through 2D δ-δ heteronuclear 1H 13C correlated NMR spectroscopy.
