Abstract Aldehydes were conveniently protected as dimethylhydrazones by stirring a mixture of the aldehyde, N,N‐dimethylhydrazine, anhydrous magnesium sulfate, and dichloromethane at room temperature. Azeotropic removal of water, formed during the course of the reaction, was not required because anhydrous magnesium sulfate functions as a water scavenger. Deprotection of aldehyde dimethylhydrazones was accomplished
摘要 通过在室温下搅拌醛、N,N-二甲基肼、无水硫酸镁和二氯甲烷的混合物,可以方便地将醛保护为二甲基腙。不需要共沸去除反应过程中形成的水,因为无水硫酸镁起到水清除剂的作用。通过在室温下搅拌醛二甲基腙和乙醛酸水溶液的混合物来完成醛二甲基腙的脱保护。醛二甲基腙的制备和脱保护反应时间随醛的结构而变化。本文中提及的商品名称或商业产品仅用于提供特定信息,并不暗示美国的推荐或认可
