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.

The present invention provides a compound of formula (I) or a salt thereof: (F ormula (I)) wherein X, L, V, R1, R2, R3 and R4, are as defined herein. The claimed compounds inhibit the enzyme 11-hydroxysteroid dehydrogenase type 2 (11-HSD2) and as a result are useful in the treatment of hyperkalemia by preventing cortisol from being oxidised to cortisone and thus allowing it to occupy the mineralocorticoid receptor, thus stimulating potassium excretion.
