Partly unsaturated 3,1-benzoxazinobenzoxazines and 1,3-benzoxazinobenzoxazines were prepared in one-pot syntheses from different cyclic 1,3-aminoalcohols by treatment with salicylaldehyde or 5-bromosalicylaldehyde, followed by formaldehyde.The structures of tetracycles 3a and 5 were determined by means of X-ray diffraction.
