Sun, Chong-Qing,Cheng, Peter T.W.,Stevenson, Jay,Dejneka, Tamara,Brown, Baerbel,Wang, Tammy C.,Robl, Jeffrey A.,Poss, Michael A.

, p. 1161 - 1164 (2007/10/03)

A general method for the synthesis of dioxolenone prodrug moieties from appropriately substituted β-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.
