  1. Предусматривается новый способ получения N4-ацил-5'-деокси-5-фтороцитидиновых производных с использованием новых 5'-деокси-5-фторо-N4,2'-О,3-О-триацилцитидиновых производных. 5-Деокси-1,2,3-три-О-ацил-β-D-рибофуранозид химически взаимодействует с 5-фтороцитозином, в результате чего получают 5'-деокси-2', 3' -ди-О-ацил-5-фтороцитидин, после чего происходит ацилирование. Ациловые радикалы полученного 5'-деокси-5-фторо-N4,2'-О,3'-О-триацилцитидиновых производных избирательно де-О-ацилируются, в результате чего получаются N-ацил-5'-деокси-5-фтороцитидиновые производные. Из фтороцитозина могут быть получены N4-ацил-5'-деокси-5-фтороцитидиновые производные при осуществлении очень небольшого числа этапов и с высокими выходами.
