Reaction Steps

Air was bubbled for 1 hour at room temperature through a suspension of 0.5 g (3 mmol) dimethyl-(2-methylpropyl)malonate and 1.73 g (5 mmol) cesium carbonate in 7 ml dimethylformamide. Stirring was continued at room temperature for 24 hours. 25 ml water was added and the mixture was extracted with diethylether. Acidification with aqueous 1 N hydrochloric acid to pH=1 and extraction with ethylacetate yielded 0.42 g (83%) (R/S)-2-hydroxy-2-isobutyl-malonic acid monomethyl ester, MS (m/e): 189.4 (M−H)−.
