Quinazolines and 1,4-benzodiazepines. XCIII. (1). Synthesis of imidazo[1,5-a][1,4]benzodiazepines from nitrooximes

Walser,Ian Fryer

, p. 551 - 558 (2007/10/02)

The displacement of the nitro group in nitrooximes by other nucleophiles was used to prepare various 2-(hydroxyimino)methyl- and 2-(methoxyimino)methyl-1,4-benzodiazepines. These compounds were converted to imidazo[1,5-α][1,4]benzodiazepines bearing a tertiary amine, methoxy or thiomethyl group in the 3-position.
