Highly Efficient and Versatile Synthesis of Lactams and <i>N</i>-Heterocycles via Al(OTf)<sub>3</sub>-Catalyzed Cascade Cyclization and Ionic Hydrogenation Reactions
The discovery and development of an efficient and versatile method for the synthesis of N-substituted lactams is described. Pyrrolindinones, piperidones, and structurally related heterocycles were formed by Al(OTf)3-catalyzed cascade cyclization and ionic hydrogenation reactions of corresponding nitrogen substituted ketoamides in good yields.

Inhibitors of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD1) show promise as drugs to treat metabolic disease and CNS disorders such as cognitive impairment. A series of 1,5-substituted 1H-tetrazole 11 beta-HSD1 inhibitors has been discovered and chemically modified. Compounds are selective for 11 beta-HSD1 over 11 beta-HSD2 and possess good cellular potency in human and murine 11 beta-HSD1 assays. A range of in vitro stabilities are observed in human liver microsome assays. (C) 2010 Elsevier Ltd. All rights reserved.
