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, Khimiya Geterotsiklicheskikh Soedinenii called Chlorination of tetrahydrofuran-2-carboxylic acid esters, Author is Zhuk, R. A.; Berzina, A.; Silina, V.; Liepins, E.; Giller, S. A., which mentions a compound: 37443-42-8, SMILESS is O=C(C1OCCC1)OC, Molecular C6H10O3, Application of 37443-42-8.
Photochem. chlorination of Me tetrahydro-2-furancarboxylate in CCl4 at -15 to -20° gave the chlorofurancarboxylate I and small amounts of the dihydrofuran II (8%) and Me 2-furancarboxylate (2%). Et tetrahydro-2-furancarboxylate was similarly chlorinated. The by-products were formed by dehydrochlorination of intermediate x-chlorination products.
After consulting a lot of data, we found that this compound(37443-42-8)Application of 37443-42-8 can be used in many types of reactions. And in most cases, this compound has more advantages.
