The new compound -dithiazepine has been synthesized from 3-(tert-Butyl)perhydro-1,3,5-triazin-2-one in 45% yield. In the reaction, urea acts as the leaving group being exchanged for the S-CH2-CH2-S fragment of the product.

Thermal Rearrangement of Some 3-Alkyl-2-aryltetrahydro-1,3-oxazine N-Oxides. Synthesis of 2-Alkyl-7-aryltetrahydro-1,6,2-dioxazepines

Several 2-alkyl-7-aryltetrahydro-1,6,2-dioxazepines 5a-i have been synthesized by a Meisenheimer-type rearrangement of 3-alkyl-2-aryltetrahydro-1,3-oxazine N-oxides4a-i. These dioxazepines have not been previously described and for the first time compounds with the tetrahydro-1,6,2-dioxazepine ring-system have been made available. The structure assigned to members of this novel heterocycle is based on elemental analysis, infrared, and 1H nmr spectral evidence. Further definitive evidence for the structure of these heterocycles is provided by an X-ray crystallographic analysis of 5c.
