A Method for the Synthesis of Acyclic Haloamines with Ring Opening of Cyclic Amines

Experimental procedure:
To a vial, Piv-protected amine (1 eq.), AgNO3 (4 eq.), (NH4)2S2O8 (4 eq.), and NCS or NBS (4 eq.) is added and dissolved in 1:9 acetone:water (0.2 M). The resulting mixture is stirred at room temperature. After 30 minutes, the reaction mixture is partitioned between EtOAc and H2O and separated. The aqueous layer is extracted with EtOAc in triplicate and the combined organic layers concentrated in vacuo. The crude mixture is then purified over silica column eluting with an EtOAc:Hex. Mixture to afford the desired haloamine product.
