Category: tetrahydropyran. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Ethyl indoline-2-carboxylate, is researched, Molecular C11H13NO2, CAS is 50501-07-0, about Synthesis of Azoles Condensed with, or Linked to, Nitroxides. Author is Bognar, Balazs; Kalai, Tamas; Gulyas-Fekete, Gergely; Lazsanyi, Noemi; Hideg, Kalman.
Nitroxides connected to indoles, tetrazoles or 1,3,4-oxadiazoles were synthesized by conventional and microwave-assisted cyclization reactions. New approaches to pyrrole-, pyrazole-, and triazole-annulated nitroxides are described. The authors showed that a Diels-Alder reaction of a N-tert-butoxycarbonyl derivative of (4,4,6,6-tetramethyl-2,4,6,7-tetrahydro-5H-pyrrolo[3,4-c]pyridin-5-yl)oxidanyl gave polycyclic scaffolds condensed with a six-membered nitroxide. The synthesis of the target compounds was achieved using as starting materials 3-cyano-2,5-dihydro-2,2,5,5-tetramethyl-1H-pyrrol-1-yloxy radical, 4-cyano-3,6-dihydro-2,2,6,6-tetramethyl-1(2H)-pyridinyloxy radical, 4-cyano-2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO derivative), 3-formyl-2,5-dihydro-2,2,5,5-tetramethyl-1H-pyrrol-1-yloxy radical and similar nitroxide radical derivatives The title compounds thus formed included triazole-nitroxide radical derivatives, benzotriazole-nitroxide radical derivatives, pyrrole-nitroxide radical derivatives, indole-nitroxide radical derivatives and related substances.
After consulting a lot of data, we found that this compound(50501-07-0)Category: tetrahydropyran can be used in many types of reactions. And in most cases, this compound has more advantages.
