[EN] The invention relates to azacyclyl-substituted arylthienopyrimidinones and their derivatives of formula (I), and their physiologically tolerated salts and physiologically functional derivatives, their preparation, medicaments comprising at least one azacyclyl-substituted arylthienopyrimidinone of the invention or its derivative, and the use of the azacyclyl-substituted aryithienopyrimidinones of the invention and their derivatives as MCH antagonists. [FR] La présente invention concerne des arylthiénopyrimidinones substituées par azacyclyle ainsi que leurs dérivés de formule (I), et leurs sels de qualité physiologique et leurs dérivés fonctionnels au niveau physiologique, leur synthèse, des médicaments comprenant au moins une arylthiénopyrimidinone substituée par azacyclyle selon l'invention ou son dérivé, et l'emploi des arylthiénopyrimidinones substituées par azacyclyle selon l'invention et de leurs dérivés en tant qu'antagonistes de la MCH.
Lewis Acid-catalyzed Reductive Etherification of Carbonyl Compounds with Alkoxyhydrosilanes
The TMSI-catalyzed reaction of aldehydes and ketones with alkoxydimethylsilanes gave unsymmetrical ethers in good to high yields. This reductive etherification is superior to the conventional method using two kinds of silicon reagents in terms of atom efficiency and ease of operation.

When benzyl, allyl, and propargyl ethers were treated with tert-butylhydroperoxide and a catalytic amount of iron(III) acetylacetonate, tert-butyl peroxyacetals were produced in good to excellent yields, via CH bond functionalization. This method is also applicable to ethylene acetals of unsaturated aldehydes to give peroxyorthoesters.
