reaction of α-(aryl)-4-morpholineacetonitriles (masked aroyl anion equivalents) with N-protected 4(5)-bromo-5(4)-nitro-1H-imidazoles gave 4-aroyl-5-nitroimidazoles which were reduced to afford 4-aroyl-5-aminoimidazoles.

A series of thieno[2,3-b]pyridin-6(7H)-one derivatives, substituted in the 3-position by an arylcarbonyl or heteroarylcarbonyl moiety, being inhibitors of p38 MAP kinase, are accordingly of use in medicine, for example in the treatment and/or prevention of immune or inflammatory disorders.
An environmentally friendly and highly active mesoporous Co(II) complex on mesoporous SBA-15 material could be used as an easily recoverable catalyst for the synthesis of α-aminonitriles from a wide range of aldehydes/ketones and primary or secondary amines with good to excellent conversions yields at room temperature under solventless conditions. The catalyst can be recovered by simple filtration and could be reused at least 10 times without loss of catalytic activity.

α-aminonitriles could be efficiently prepared from various aldehydes/ketones and primary or secondary amines using a highly active and stable Co(II) complex supported on different mesoporous supports at both room temperature and low temperature microwave irradiation undersolventlessconditions. Catalysts were also highly reusableunder the investigated reactionconditions and could be reused at least 10 times
