Summary

Alkylation of 5′-O-tritylthymidine with dialkylaminoalkyl chlorides in the presence of sodium hydride yields 3′-O-dialkylaminoalkyl-5′-O-tritylthymidine derivatives2 which were treated with an excess of iodomethane to afford the corresponding quaternary ammonium derivatives3. Deprotected nucleosides4 and6 were obtained by refluxing3 and2, respectively, in 80% acetic acid. When the compounds2–4 and6 were investigated for activity against HSV and HIV, the trityl derivatives2a and2c were found active against HSV.

Zusammenfassung

Alkylierung von 5′-O-Tritylthymidin mit Dialkylaminoalkylchloriden in Gegenwart von Natriumhydrid ergab 3′-O-Dialkylaminoalkyl-5′-O-tritylthymidinderivate2, die mit einem Überschuß an Iodmethan zu den entsprechenden quartären Ammoniumderivaten3 umgesetzt wurden. Die entschützten Nucleoside4 und6 wurden durch Kochen von3 bzw.2 in 80% iger Essigsäure unter Rückfluß erhalten. Bei der Untersuchung von2–4 und6 im Hinblick auf ihre Wirksamkeit gegen HSV und HIV wurde bei den Tritylderivaten2a und2c Aktivität gegen HSV festgestellt.
