protocol for the direct reductive amination of aldehyde bisulfite adducts is reported. Bisulfite adducts of aliphatic and aromatic aldehydes, on treatment with an organic base under non-aqueous conditions liberate the aldehyde in situ, which then undergoes efficient reductive amination with amines in the presence of sodium triacetoxyborohydride. Bisulfite adducts - reductive amination - sodium triacetoxyborohydride
报道了一种新颖的一锅法用于醛亚硫酸氢盐加合物的直接还原胺化。在非水条件下用有机碱处理时,脂族和芳族醛的亚硫酸氢盐加合物会原位释放醛,然后在三乙酰氧基硼氢化钠的存在下用胺进行有效的还原胺化。 亚硫酸氢盐加合物-还原胺化-三乙酰氧基硼氢化钠
