The palladium-catalyzed hydroarylation of N-methyl-substituted tricyclic imides was studied in order to find a new stereoselective access to a series of new exo-aryl(hetaryl)-substituted tricyclic N-methylimides.

The synthesis of new tricyclic vinylcyclobutanes is reported. These compounds were prepared in good yields from the ketones via a two step Peterson olefination. Under conditions of photoinduced electron transfer some tricyclic vinylcyclobutanes show interesting skeleton rearrangements.

Overdoses of tricyclic antidepressants are among the commonest causes of drug poisoning seen in accident and emergency departments. This review discusses the pharmacokinetics, clinical presentation and treatment of tricyclic overdose.

A Ni/N-heterocyclic carbene catalyst couples diynes to the C(α)-C(β) double bond of tropone, a type of reaction that is unprecedented for metal-catalyzed cycloadditions with aromatic tropone. Many different diynes were efficiently coupled to afford [5-6-7] fused tricyclic products, while [5-7-6] fused tricyclic compounds were obtained as minor byproducts in a few cases. The reaction has broad s...

Tricyclic antidepressants have not been explicitly studied in the conservative treatment of lumbar spinal stenosis. A retrospective chart review was conducted in a subset of patients with chronic low back pain and lumbar spinal stenosis managed with low dose tricyclic antidepressants. Of 26 patients, 20 reported improvement in back pain. The majority of patients reported improvement with an ini...

bandwidth labelling is a well known research area in graph theory. we provide a new proof that the bandwidth of mobius ladder is 4, if it is not a $k_{4}$, and investigate the bandwidth of a wider class of mobius graphs of even strips.
