Methods The target compound(1)was prepared from erythromycin A(3)and hydroxylaminehydrochloride in a novel acid base buffer.
方法在酸碱缓冲溶液中由红霉素A（3 ）与盐酸羟胺缩合生成1。
2
Aromatic dinitriles were prepared with excellent yields by refluxing the corresponding aromatic dialdehydes with hydroxylaminehydrochloride in 85% formic acid or glacial acetic acid.
芳香族二醛与羟胺盐酸盐在85%甲酸或冰醋酸中回流可制备相应的芳香族二腈。方法简便，产率高。
3
The radical 2 as an electron donor underwent a rapid photo-induced redox reaction in carbon tetrachloride leading to the formation of the corresponding piperidine hydroxylaminehydrochloride.
