Abstract
An unprecedented method for the synthesis of dichlorinated and dibrominated 2-amino-substituted chromanones is developed by employing enaminones and NCS/NBS as starting materials under microwave irradiation. The reactions proceed quickly to deliver products without using any catalyst or additive, thus providing practical access to 3,3-dihalogenated 2-aminochromanones.

Abstract
The first total synthesis of the pyranoisoflavone kraussianone 1 (1) is described. The key steps involved the Suzuki-Miyaura reaction for the construction of the isoflavone core and the regioselective formation of the dimethylpyran scaffolds to the phloroglucinol (ring A) and resorcinol (ring B) moieties of kraussianone 1 (1). This route also provided access to the related isoflavones eriosemaone D (2) and genistein (3) via simple structural modifications.

Abstract
Several synthetic Vitamin E derivatives are strong inhibitors of lipid peroxidation induced in rat liver microsomes either chemically by ferrous ions and ascorbate or enzymatically by NADPH and carbon tetrachloride. The relative activities of these inhibitors are consistent with their intrinsic antioxidant properties, as peroxyl radicals scavengers. Among them, a 3,4-dihydro-6-hydroxy-2H-1-naphtopyran with IC50 around 0.08 microM is one of the most potent yet known inhibitor of lipid peroxidation.
