Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Organic & Biomolecular Chemistry called Continuous flow as an enabling technology: a fast and versatile entry to functionalized glyoxal derivatives, Author is Lima, Fabio; Meisenbach, Mark; Schenkel, Berthold; Sedelmeier, Joerg, which mentions a compound: 118994-89-1, SMILESS is O=C(C1=CN=CO1)OCC, Molecular C6H7NO3, Quality Control of Ethyl oxazole-5-carboxylate.
Two complementary strategies employing organolithium chem. for the synthesis of glyoxal derivatives RC(O)R1R2 (R = methoxymethyl, 3,5-difluorophenyl, pyridin-2-yl, quinolin-6-yl, etc.; R1 = Cl, OEt, H; R2 = Cl, OEt, 3-chlorophenyl) were reported. Micro-mixer technol. allows for the generation of unstable organometallic intermediates and their instantaneous in-line quenching with esters as electrophiles RC(O)OEt. Selective mono-addition was observed via putative stabilized tetrahedral intermediates. Advantages offered by flow chem. technologies facilitate direct and efficient access to masked 1,2-dicarbonyl compounds while mitigating undesired byproduct formation. These two approaches enable the production of advanced and valuable synthetic building blocks for heterocyclic chem. with throughputs of grams per min.
