[EN] Novel water-soluble C-ring analogues of 20(S)-camptothecin having general formula (1). All the compounds of formula (1) are prepared from the compounds of general formula (2) having 20(S)-chiral carbon. The compounds of formula (1) possess potent anti-cancer and anti-viral properties. The invention also provides an alternate process for the preparation of known C-5 substituted compounds of formula (1). [FR] Nouveaux analogues de noyaux C hydrosolubles de 20(S)-camptothécine présentant la formule générale (1). Tous les composés de la formule (1) sont préparés à partir des composés de la formule générale (2) présentant un carbone 20(S)-chiral. Les composés de la formule (1) présentent des propriétés anticancéreuses et antivirales puissantes. L'invention concerne également un autre procédé de préparation de composés à substitution C-5 connus de la formule (1).

5‐aryl‐(20S)‐camptothecin derivatives were synthesized by the reaction of 5‐hydroxy‐(20S)‐camptothecin with aromatic hydrocarbons under Friedel‐Craft reaction conditions in moderate to good yield as diastereomeric pairs. The methodology was then extended for the synthesis of 5‐amido‐(20S)‐camptothecin derivatives by reacting 5‐hydroxy‐(20S)‐camptothecin with alkyl and aryl nitriles under Ritter typereaction conditions
