α-Amino keto acetals (β,β-dialkoxyamines) are synthesized in a regiospecific way by the reaction of α-bromo-α-chloro ketimines with sodium borohydride in methanol. As α-bromo-α-chloro ketimines are formed regiospecifically from α,α-dihalogenated ketones, derived from the corresponding ketones, this methodology entails a regiospecific synthesis of α-amino keto acetals from ketones.
δ-溴-δ-氯酮亚胺与硼氢化钠在甲醇中的反应以区域特异性方法合成了δ-氨基酮缩醛(δ²,δ²-二烷氧基胺)。由于δ-溴-δ-氯酮亚胺是由δ,δ-二卤化酮(由相应的酮衍生而来)按区域特异性生成的,因此这种方法需要按区域特异性从酮合成δ-氨基酮缩醛。
