A Systematic Study of the Relationship between Molecular and Crystal Structure among 3,5-Diazabicyclo[2.2.2]octane-2,6-diones was written by Brewer, Jason T.;Parkin, Sean;Grossman, Robert B.. And the article was included in Crystal Growth & Design in 2004.Synthetic Route of C11H20O4 This article mentions the following:
A simple, convergent synthesis of 3,5-diazabicyclo[2.2.2]octane-2,6-diones (bicyclic N,N’-diacylaminals) has been developed, providing access to a large series of compounds differing only in their substituents at the bridgehead positions. These compounds crystallize in several different forms, but always in such a way that each mol. forms four hydrogen bonds. The sheer number of bicyclic amidals that can be synthesized and crystallized provides an opportunity to elucidate crystal-engineering structure-structure relationship (SSR) principles. In the experiment, the researchers used many compounds, for example, Diethyl isobutylmalonate (cas: 10203-58-4Synthetic Route of C11H20O4).
Diethyl isobutylmalonate (cas: 10203-58-4) 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. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Synthetic Route of C11H20O4
