N1,N2-Dimethoxy-N1,N2-dimethyloxalamide (cas: 106675-70-1) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.Synthetic Route of C6H12N2O4

Stereoselective sulfoxide directed reduction of 1,2-diketo-derivatives to enantiomerically pure syn and anti 1,2-diols was written by Solladie, Guy;Hanquet, Gilles;Rolland, Catherine. And the article was included in Tetrahedron Letters in 1997.Synthetic Route of C6H12N2O4 This article mentions the following:

A new route to enantiopure syn and anti 1,2-diols is described from oxalyl-di-(N-methyl-N-methoxyamide) via corresponding β-ketosulfoxide. This is the first report of the stereoselective reduction of a γ-keto-β-hydroxysulfoxide. In the experiment, the researchers used many compounds, for example, N1,N2-Dimethoxy-N1,N2-dimethyloxalamide (cas: 106675-70-1Synthetic Route of C6H12N2O4).
