Ade, Eugen et al. published their research in Tetrahedron Letters in 1980 | CAS: 1190-39-2

malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Safety of malonic acid dibutyl ester

Directed resolution of enantiomers by liquid chromatography of diastereomeric derivatives. 7. Syntheses of the stereoisomers of 17,21-dimethylheptatriacontane – sex recognition pheromone of the tsetse fly was written by Ade, Eugen;Helmchen, Guenter;Heiligenmann, Gudrun. And the article was included in Tetrahedron Letters in 1980.Safety of malonic acid dibutyl ester This article mentions the following:

(R,R)- And (S,S)-Me(CH2)15CHMe(CH2)3CHMe(CH2)15Me [(R,R)- and (S,S)-I] were both prepared in nine steps from (±)-Me(CH2)15CHMeCO2H via diastereomeric amides and in eight steps in an asym. preparation from the ester II [R = Me for (S,S)-I; R = Me(CH2)15 for (R,R)-I]. (R,S)-I was also prepared In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Safety of malonic acid dibutyl ester).
