Pyridine-2-thiones, 2-pyrone phenylhydrazones, and 2-pyridones from 2-pyrones
Abstract
Various 5-aryloxypyran-2-thiones, 2-pyridones, and 1-amino-2-pyridones have been prepared. The pyran-2-thiones were converted into pyridine-2-thiones and phenylhydrazones. Some derivatives of 6-p-bromophenyl-5-phenoxy-4-phenyl-2-pyrone (Ia) are described.
