The present invention relates to novel heterocyclic compounds. The invention is also directed to compounds which are modulators of the metabotropic glutamate receptors (mGluR), preferably of the metabotropic glutamate receptor subtype 7 ("mGluR7"). The present invention also relates to pharmaceutical composition comprising such compound and their use for the treatment of prevention of disorders associated with glutamate dysfunction.

Azo compounds (RN = NR′) are an important class of organic molecules that find wide application in organic synthesis. Herein, we report an efficient, practical and metal-free oxidation of hydrazines (RNH-NHR’) to azo compounds using 5 mol% HBr and hydrogen peroxide as terminal oxidant. This new method has been demonstrated by 40 examples with excellent yields. In addition, we showcased two examples
A general strategy for the identification of selective cholesterol transport protein inhibitors through the synthesis of a diverse sterol-inspired compound collection is presented. Fusion of a primary sterol scaffold to diverse secondary natural product-derived scaffolds afforded hits against all of the Aster family of cholesterol transport proteins and selective inhibitors of Aster-C.

Microwave irradiation promotes the conversion of enaminoketones formed in situ into a variety of heterocycles by reaction with the appropriate bidentate nucleophile. The advantages of the method over previous approaches are short reaction times and facile purification by precipitation of the products in aqueous media. Moreover the convenient one-pot procedure makes these syntheses particularly suitable for library production. Organic reactions in aqueous media have become of great interest as water is not only more environmentally friendly, but also because organic reactions in water often display unique reactivity and selectivity.
