Oxygen heterocycles. Part XIII. From 3-arylisocoumarins to 3-arylisoquinolines and 4-aryl-5H-2,3-benzodiazepines
Abstract
The reaction of ammonia, methylamine, or hydrazine hydrate with a large number of 3-arylisocoumarins has been investigated with a view to the preparation of derivatives of isoquinoline and 5H-2,3-benzodiazepine, and the determination of the structure of the parent isocoumarins, using infrared spectroscopy.
