A series of some 1, 3-oxazine amine derivatives including 4-(1-naphthyl)-5,6-dihydro-6-(substituted phenyl)-oxazine-2-amines has been synthesised by lsolid SiO2-H3PO4 catalyzed solvent-free cyclization of aryl chalcones and urea under microwave irradiation. The yields of the oxazines were more than 80%. The synthesised oxazine amines were characterized by their physical constants, analytical and spectroscopic data. The antimicrobial activities of these oxazine derivatives have been studied using Bauer-Kirby method.

This invention relates to compounds which have the ability to act as agonists for the binding of divalent copper ions to amyloid precursor protein (APP) and to methods of identifying such compounds by using the three-dimensional structure of the copper-binding domain of APP.
Aza‐Dipyrrinate Stabilized Compounds with a Low‐Valent Main Group Element
The first examples of a-DPM ligand stabilized compounds containing a low-valent main groupelement are isolated and characterized. Interestingly, the absorption maxima of these a-DPM stabilized germylenes are highly red-shifted above 640 nm.
