Some 1,4-benzoxazino[2,3-b]phenoxazines derivatives as antibacterial, muscle relaxant and hypnotic agents

1,4-Benzoxazino[2,3-b]phenoxazines are synthesised by condensation of substituted anilines with halobenzoquinones followed by cyclisation. These compounds are screened for their antibacterial, muscle relaxant and hypnoticactivities.
