The von Braun reaction (the reaction of cyanogen bromide with tertiary amines) was applied to a series of functionalized N ‐alkyl‐substituted azetidines. This reaction mainly led to the cleavage of the strained four‐membered ring to produce 3‐bromo N ‐alkyl cyanamides in good yields with variable regioselectivity. The resulting cyanamide products were then employed as original building blocks for the synthesis of nitrogen heterocycles.
