A series of tricyclic benzimidazole derivatives, in particular dihydro-1H- imidazo [1,2-a]benzimidazo le, dihydro-1H-pyrrolo [1,2-a]benzimidazo le, dihydro-1H- pyrazino[1,2-a]benzimidazole, dihydro-1H-[1,4]oxazino[4,3-a]benzimidazole and dihydrothiazolo[3,4-a]benzimidazolem, and analogues thereof, being potent modulators of human TNFa activity, are accordingly of benefit in the treatment and/or prevention of various human ailments, including autoimmune and inflammatory disorders; neurological and neurodegenerative disorders; pain and nociceptive disorders; cardiovascular disorders; metabolic disorders; ocular disorders; and oncological disorders.
This manuscript describes the synthesis of γ-lactam from the nitrogen insertion reaction of cyclobutanones using an oxime as an aminating reagent with a catalytic amount of Brønstedacid. This method was employed with a more stable oxime reagent, which is a precursor analog of hydroxylamine derivatives with explosive properties. The reaction was tolerated by various substituted cyclobutanones and less
