chosen as a point of departure for the design of 4(5)-[(3,4-dihydro-2-naphthalenyl)methyl]-4,5-dihydroimidazole (4a), which displayed the desired profile: alpha(2A)-adrenoceptor antagonist properties and serotonin/noradrenaline uptake inhibition. From this original molecule, a series of derivatives was designed and synthesized, encompassing substituted as well as rigid analogues. Structure-activity relationships

Cyclic enamides were prepared in one step from tetralone and chromanone derivatives and primary amides under acidic conditions. The enantioselectivehydrogenation of these enamides bearing an endocyclic trisubstituted carbon-carbon double bond was performed at room temperature in the presence of ruthenium catalysts. On the one hand, the nature of the amide group had little influence on the enantioselectivity

Rhodium (II) acetate-catalysed cyclisation of α-diazoketones derivedfrom 3-arylpropionic acid produces bicyclo[5.3.0]decatrienones or 2-tetralones depending on the substitution pattern of the aryl ring: the former products are transformed into the latter by catalytic amount of trifluoroacetic acid.

4-Aryl-2-hydroxybutanal diethylacetal, prepared from the reaction of benzyl Grignard reagent and glycidaldehyde diethylacetal, was treated with titanium tetrachloride to give 2-tetralone in good yield. This highly efficient transformation involves tandem oxonium formation, intramolecular Friedel–Crafts alkylation, deethoxylation, and tautomerization in the same flask.
A unique copper-catalyzed aerobic oxidative C–C bondcleavage of simple unstrained ketones with air and amines has been developed. In this chemistry, amides and oxo amides are easily synthesized through the selective C–C bondcleavage of simple ketones or unstrained cycloketones. The broad substrate scopes and use of an inexpensive copper catalyst and green molecular oxygen as an oxidant as well as
