1,3-Dicarbonyl compounds (1) were efficiently oxygenated at the α-position with cesium salts, such as CsF or Cs2CO3 (0.1 Meq) in DMF at room temperature. Reaction of malonate derivatives (1a, b) with excess amount (2 Meq) of Cs2
Synthesis of 3-amino(alkoxy)-2,4-dioxo-1,3-oxazolidine-5-carboxylates from tartronic esters

The reaction of tartronic esters (1a-d) with 1,1′-carbonyl-di-(1,2,4-triazole), hydrazines or hydroxylamines produces 3-amino/3-alkoxy(aralkoxy)-2,4-dioxo-1,3-oxazolidine-5-carboxylic esters (5,6) which are structurally related to the fungicides Famoxadone (I) and Chlozolinate (II). Under suitable conditions the carboxylic ester of 6 can be converted to a carboxamide (7), carbohydrazide (8) or carbohydroxamic acid (9).
