Novel dithia-aza-norbornanes as 'stiff' bicyclic dithiazines
Kurchan, Alexei N.,Wade, Edmir,Kutateladze, Andrei G.
, p. 1731 - 1733 (2003)
Addition of lithiated 4,5-dihydro-1,3,5-dithiazines to in situ generated N-silylimines in THF produces 2-(α-aminoalkyl)dithiazines, which rearrange into 3,5-dithia-1-azabicyclo[2.2.1]heptanes upon aqueous workup. These novel bicyclic dithiazines can in tu
