Abstract
We obtained perhydro-1,2,3-oxathiazine 2,2-dioxides by cyclization of 4-N-benzylamino-4-tetramethylene(phenyl-, methylphenyl-, dimethyl)but-1-enes in conc. H2SO4 at 25°C. When treated with an alcoholic solution of base, the oxathiazines are converted to 2-substituted and spiro-annelated 1-benzyl-4-methylazetidines.
