RISSynthesis of new derivatives of 2-Substitueted 4-(4-methyl-12Hpyrimido[4,5:5,6][1,4]thiazino[2,3-b]quinoxalin-2-yl)
Nitrogen-containing heterocycles are undoubtedly one of the most important targets in organic chemistry. They are widely distributed in natural products and in pharmaceutical agents, and numerous studies for their chemistry ...
Synthesis of Thiazino[2,3-b]quinoxaline as a New Heterocyclic System
Heterocyclic compounds have a wide range of applications but are of particular interest in
medicinal chemistry and this improve the discovery and development of much heterocyclic
chemistry and methods. The ...
One-pot, procedure for the preparation of some thiazino[2,3-b]quinoxaline derivatives
An efficient and convenient synthesis of new thiazino[2,3-b]quinoxaline derivatives has been developed by employing a one-pot cyclo-condensation of several α-haloketones and 3-aminoquinoxaline-2-thiol in acetic acid. A ...
An alternative approach to the synthesis of new pyrimido[5′,4′:5,6][1,4] thiazino[2,3-b]quinoxaline derivatives
An alternative approach to the synthesis of a series of new pyrimido[5′,4′:5,6][1,4]thiazino[2,3-b]quinoxaline derivatives is described. Reaction of 5‑bromo-2,4-dichloro-6-methylpyrimidine and 3‑aminoquinoxaline-2-thiol ...
