gaseous formaldehyde is described. Moreover, under these conditions, bromonitroalkanes were converted into the corresponding α-monohydroxymethylated nitroalkanes, which are precursors of the corresponding α-amino acids. Considering the easy transformation of ketones into bromonitroalkanes, this represents a method for the formal synthesis of α-amino acids from ketones.
描述了一种非常简单、安全和有效的方法,用于在 annyarous 条件下避免使用气态甲醛的 hyaroxymethylation 或 2-溴酯和内酯。此外,在这些条件下,溴硝基烷烃转化为相应的 α-单羟甲基化硝基烷烃,它们是相应 α-氨基酸的前体。考虑到酮容易转化为溴硝基烷烃,这代表了一种从酮正式合成 α-氨基酸的方法。
