Chemical synthesis of prodrugs derived from 5,6-dihydro-5-azacytosine and its nucleosides using vinyl esters
Janská, Lucie ; Blažek, Jiří ; Mařák, David ; Otmar, Miroslav ; Krečmerová, Marcela
New strategy for synthesis of amide prodrugs without protecting groups for 5,6-dihydro-5-azacytosine and its nucleosides was developed and introduced. Vinyl esters were used as acyl donor and the reactive amino group on the heterocycle functions as nucleophile.
Enzymatic synthesis of ester prodrugs of DHPA and related compounds by lipases
Blažek, Jiří ; Kaiser, M. M. ; Zarevúcka, Marie ; Králová, B. ; Krečmerová, Marcela
An enzymatic method was used for esterification of DHPA and related compounds with vinyl esters and catalyzed by different lipases in non-aqueous media (DMF). Esters of DHPA and other compounds could be synthesized and purified in satisfactory yields.
