A new protocol for the synthesis of vicinal bromoamines from electron deficient olefin(β,β-Dicyanostyrene and a-cyano ethyl cinnamate)/Amide/NBS was developed in one pot.In the presence of anhydrous base,electron deficient olefins reacted with NBS and amide which can generate the vicinal haloamine compounds smoothly in good to excellent yield(up to 93%yield)at room temperature without the protection of inert gas in CH2Cl2 or CH3OH.26 different structural electron deficient olefins reacted with 7 different s...
