A series of α-bromo 3-amino-5,5-dimethylcyclohex-2-en-1-ones 2a-g and α-bromo β-enamino compounds 4a, b have been conveniently prepared using NBS supported on montmorillonite (K-10). Other reaction conditions such as di-tert-butyl peroxide/NBS/CCl4, and Br2/CH2Cl2 were also studied for 3-amino-5,5-dimethylcyclohex-2-en-1-ones 1b, e, g resulting in a mixture of mono and di-brominated compounds 5b, f, g and 6b, e, g.
使用蒙脱石(K-10)支撑的 NBS 方便地制备了一系列δ-溴 3-氨基-5,5-二甲基环己-2-烯-1-酮 2a-g 和δ-溴 ²-烯氨基化合物 4a, b。对于 3-氨基-5,5-二甲基环己-2-烯-1-酮 1b、e、g,还研究了其他反应条件,如二叔丁基过氧化物/NBS/CCl4 和 Br2/CH2Cl2,结果制备出了单溴和双溴化合物混合物 5b、f、g 和 6b、e、g。
