Electroreduction of 3-bromo- and 3, 3-dichloro-β-lactams 1 carried out at the potential of the first voltammetric peak and in the presence of acetic anhydride gives 3-acetyl-β-lactams 2. The electrosynthesis is highly stereoselective, as only the acetyl derivative with trans configuration is formed.
在第一个伏安峰的电势下,在乙酸酐的存在下,进行3-溴-和3,3-二氯-β-内酰胺2的电还原,得到3-乙酰基-β-内酰胺2。电合成是高度立体选择性的,因为仅形成具有反式构型的乙酰基衍生物。
