A general synthesis of dioxolenone prodrug moieties
摘要:
A general method for the synthesis of dioxolenone prodrug moieties from appropriately substituted beta-ketoesters is described. This novel and versatile sequence allows for the synthesis of alkyl- or aryl-substituted dioxolenone alcohols 8 or bromides 9. Coupling of the bromides 9 to prepare bis-dioxolenone phosphonate prodrug esters is also presented. (C) 2002 Elsevier Science Ltd. All rights reserved.
