Description
| - A novel modular, efficient and practical methodology for the preparation of 3- and 4-substituted phenyl and aniline C-ribonucleosides was developed. The key intermediates were synthesized in two steps from TBS-protected ribonolactone in 75% and 66% yields, respectively, as pure beta-anomers. The bromophenyl intermediates were subjected to a series of palladium catalyzed cross-coupling, aminations and alkoxylation reactions to give, after deprotection a series of free 1 beta-(3- and 4-alkyl, -aryl, -amino -alkoxyphenyl and -hetaryl substituted phenyl)-C-ribonucleosides (20 examples).

- Byla vyvinuta nová modulární, efektivní a praktická syntéza 3- a 4-substituovaných fenylových a anilinových C-ribonukleosidů. Oba klíčové intermediáty byly syntetizovány ve dvou krocích, vycházející z TBS-chráněného ribonolaktonu, v 75% a 66% výtěžku jako čisté beta-anomery. 3- a 4-bromfenylové intermediáty přetransformované pomocí palladiem katalyzovaných cross-coupling, aminačních a alkoxylačních reakcí, poskytly po následné deprotekci volné 1 beta-(3- a 4-alkyl, -aryl, -amino, -alkoxyfenyl a -hetaryl substituované fenyl)-C-ribonukleosidy (20 příkladů).
