Chemie der Amino‐oxime, XIX. Umsetzung von β‐Benzylamino‐oximen mit Sulfurylchlorid

Chemistry of Amino Oximes, XIX. — Reaction of β‐Benzylamino Oximes with Sulfuryl Chloride 3,4‐Dihydro‐2 H ‐1,2,6‐thiadiazine 1,1,6‐trioxides 2 were prepared from anti ‐β‐benzylamino oximes 1 and sulfuryl chloride. Tetrahydro‐2 H ‐1,2,6‐thiadiazin 1,1‐dioxides 3 were formed by reduction with NaBH 4 and β‐hydroxylimino sulfamic acid derivatives by hydrolysis, alkoholysis, and aminolysis with secondary amines. With primary amines, 2 afforded pyrazolines 7 ; syn ‐β‐benzylamino oximes 9 and sulfuryl chloride yielded pyrazolines 10 .
