N1,N2-Dimethoxy-N1,N2-dimethyloxalamide (cas: 106675-70-1) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Recommanded Product: 106675-70-1

New and regioselective synthesis of 4-ylidenetetronic acids by Lewis-acid-catalyzed cyclization of 4-alkoxy-bis-(trimethylsiloxy)-1,3-dienes with oxalyl chloride was written by Langer, Peter;Eckardt, Tobias. And the article was included in Synlett in 2000.Recommanded Product: 106675-70-1 This article mentions the following:

A new approach for the synthesis of 4-ylidenetetronic acids is reported which involves Me3SiO3SCF3-catalyzed regio- and stereoselective cyclization of 4-alkoxy bis(trimethylsiloxy) 1,3-dienes with oxalyl chloride and subsequent chemoselective deprotection of the 3-OH group. In the experiment, the researchers used many compounds, for example, N1,N2-Dimethoxy-N1,N2-dimethyloxalamide (cas: 106675-70-1Recommanded Product: 106675-70-1).
