A method for producing N-protected heterocyclic compounds such as 1-alkoxycarbonyl-3-aminopyrrolidines through position-selective reaction at the nitrogen atom that constitutes the hetero ring of a nitrogen-containing saturated heterocyclic compound having two nitrogen atoms such as 3-aminopyrrolidine. A dialkyl dicarbonate (ROCO-O-COOR) is reacted with a nitrogen-containing saturated heterocyclic compounds having two nitrogen atoms, at pH of from 9 to 14 to obtain a high-purity 1-alkoxycarbonyl nitrogen-containing saturated heterocyclic compound.
一种通过在具有两个氮原子的含氮饱和
杂环化合物(如
3-氨基吡咯烷)中构成杂环的氮原子上进行位置选择性反应来生产 N 保护
杂环化合物(如 1-烷氧羰基-
3-氨基吡咯烷)的方法。将二烷基二
碳酸酯(ROCO-O-COOR)与具有两个氮原子的含氮饱和
杂环化合物在 pH 值为 9 至 14 的条件下进行反应,可得到高纯度的 1-烷氧基羰基含氮饱和
杂环化合物。
