## Abstract A tandem reduction‐reductive amination reaction has been applied to the synthesis of (±)‐4‐alkyl‐2,3,4,5‐tetrahydro‐1,5‐benzoxazepines and (±)‐4‐alkyl‐1‐benzoyl‐2,3,4,5‐tetrahydro‐1__H__‐1,5‐benzodiazepines. The nitro aldehydes and ketones required for 1,5‐benzoxazepine ring closures we
Electron ionization mass spectra of a series of 2,4-disubstituted dihydro-and tetrahydro-1,5-benzodiazepines are discussed. The fragmentation of these compounds is dominated by ring contractions of diazepine, which give both five-and six-membered rings, benzimidazoles and quinoxalines. Tetrahydro co
