Regioselective preparation of 2′, 3′-di-O-acylribonucleosides carrying lipophilic acyl groups through a lipase-catalysed alcoholysis
Candida antarctica B lipase-catalysed alcoholysis of 2′, 3′, 5′-tri-O-hexanoyluridine (1a), 2′, 3′, 5′-tri-O-dodecanoyluridine (1b), 2′, 3′, 5′-tri-O-hexanoylinosine (1c) and 2′, 3′, 5′-tri-O-dodecanoylinosine (1d) proceeded regioselectively to produce the corresponding 2′, 3′-di- O-acylribonucleosi...

| Summary: | Candida antarctica B lipase-catalysed alcoholysis of 2′, 3′, 5′-tri-O-hexanoyluridine (1a), 2′, 3′, 5′-tri-O-dodecanoyluridine (1b), 2′, 3′, 5′-tri-O-hexanoylinosine (1c) and 2′, 3′, 5′-tri-O-dodecanoylinosine (1d) proceeded regioselectively to produce the corresponding 2′, 3′-di- O-acylribonucleosides 2a-d, providing a simple and efficient access to these new lipophilic compounds. Contrasting to the alcoholysis, enzymatic hydrolysis of 1a-d using different enzymes and experimental conditions did not proceed regioselectively. |
