In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Chiral ammonium hypoiodite salt-catalyzed enantioselective oxidative cycloetherification to 2-acyl tetrahydrofurans, published in 2016, which mentions a compound: 37443-42-8, Name is Methyl tetrahydrofuran-2-carboxylate, Molecular C6H10O3, Computed Properties of C6H10O3.
Chiral quaternary ammonium hypoiodite salt-catalyzed enantioselective oxidative cycloetherification of δ-hydroxyketone derivs was achieved . The corresponding 2-acyl tetrahydrofurans were obtained in high chem. yield with high enantioselectivity.
Compound(37443-42-8)Computed Properties of C6H10O3 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(Methyl tetrahydrofuran-2-carboxylate), if you are interested, you can check out my other related articles.
