, p. 412 - 414 (1998)
The synthesis of β-keto esters has been performed in good yield by reacting excess methyl acetoacetate with barium oxide, acylating the resulting barium complex with acid chloride, and then cleaving the α-acyl β-keto ester with methanol at a mild temperature. Using this new procedure, various β-keto esters were prepared. Thus, methyl 4-phenyl-3-oxobutanoate, methyl 3-phenyl-3-oxopropionate, methyl 4-cyclohexyl-3-oxobutanoate, and methyl 3-oxooctadecanoate were prepared from methyl acetoacetate and the corresponding acid chloride in 69%, 84%, 67%, and 74% yields, respectively.
Asymmetric Reduction of 3-Oxo-octadecanoic Acid with Fermenting Baker's Yeast. An Easy Synthesis of Optically Pure (+)-(2R,3R)-Corynomycolic Acid

, p. 1368 - 1369 (1987)
Optically pure (+)-corynomycolic acid has been synthesized from methyl acetoacetate by a route including asymmetric reduction of 3-oxo-octadecanoic acid with baker's yeast as a key step.

Here, we report a systematic comparison of different methods for the transesterification of 3-oxo fatty acid alkyl esters to the corresponding nicotinyl esters. A simple method producing the target esters in high yields and purity has been developed. Nicotinyl esters are of interest for mass spectrometry analysis of fatty acids. Also, the hydrophilic head group of nicotinyl esters can be used as the basis for the preparation of liposome-building molecules.

β-Ketoesters are valuable building blocks for the synthesis of compounds with different biological activities. In this study, a series of fatty β-ketoesters were obtained from fatty acids and Meldrum's acid using N,N-dicyclohexylcarbodiimide and dimethylaminopyridine. In addition, we demonstrate for the first time the synthesis of new fatty β-ketoesters from oleic (cis-C18:1), elaidic (trans-C18:1), ricinoleic (cis-C18:1, 12-OH), linoleic (cis,cis-C18:2), and linolenic (cis,cis,cis-C18:3) acids in good yields.
