yields under carefully controlled conditions from aromatic nitro-compounds bearing hydroxyalkyl substituents jointed to the ring, either directly, or through various linking atoms or groups. Reduction of the products to primary amines, without loss of the labile ester groups, is frequently accompanied by serious practical difficulties, and in some cases, it was not possible to obtain the amines in
甲烷磺酰基,对甲苯磺酰基和类似的酯可以在精心控制的条件下从具有直接或通过各种连接原子或基团键合到该环上的羟基烷基取代基的芳族硝基化合物以良好的产率获得。在不损失不稳定的酯基的情况下,将产物还原成伯胺常常伴随着严重的实际困难,并且在某些情况下,不可能获得纯态的胺。
