Ironing it out: The straightforward N‐alkylation using alcohols and iron/aminoacid catalysis is described (see scheme). The reaction does not proceed by the conventional “borrowing hydrogen” mechanism, but appears to involve a substitution pathway (SN) at the sp3 carbon atom bearing the hydroxy group of the alcohol. Developing a catalyst that is effective at a near neutral pH was key to the successful
1,2 Diamido cycloalkyl compounds that are sodium channel blockers; pharmaceutical compositions that include an effective amount of the aryl-link-aryl thiazolidin-dione and aryl-link-aryl oxazolodine-dione compounds and a pharmaceutically acceptable carrier; and a method of treatment of acute pain, chronic pain, visceral pain, inflammatory pain, or neuropathic pain, as well as irritable bowel syndrome, Crohns disease, epilepsy, partial and generalized tonic seizures, multiple sclerosis, bipolar disease, and tachy-arrhythmias by the administration of an effective amount of aryl-link-aryl thiazolidine-dione and aryl-link-aryl oxazolodine-dione compounds, either alone, or in combination with one or more therapeutically active compounds, are described.
