Processes for preparing (((3aR,6aS)-5-(4,6-dimethylpyrimidin-2-yl)hexahydropyrrolo[3,4-c]pyrrol-2(1H)-yl)(2-fluoro-6-(2H-l,2,3-triazol-2- yl)phenyl)methanone are described, which are useful for commercial manufacturing. Said compound is an orexin receptor modulator and may be useful in pharmaceutical compositions and methods for the treatment of diseased states, disorders, and conditions mediated by orexin activity, such as insomnia and depression.
New compounds belonging to the structural formula (I) are described.
in which R1, R2, A, Y and X are specified in the description, useful in the treatment of cholestasis and substantially devoid of antibacterial activity. The synthesis process of said compounds, the pharmaceutical compositions containing them and their use in therapy are also described.

[reaction: see text] Optically active 4-substituted 2-oxetanones provide conduits for preparing 2,3-dihydro-4H-pyrone heterocycles. Enantioenriched beta-lactones are prepared by asymmetriccatalyticacylhalide-aldehydecyclocondensationreactions. Hydrazone anion-mediated beta-lactone ring opening and ensuing cyclization-dehydroamination of the derived beta-ketohydrazone afford the desired dihydropyrones
