A simple, convenient and one-pot transformation of the acetates of Baylis–Hillman adducts into substituted γ-lactams, that is, (E)-5-alkyl-3-arylidenepyrrolidin-2-ones via treatment with nitroalkanes in the presence of a base, followed by reductive cyclization, using Fe/AcOH, is described.
一种简单,方便且一锅式的方法,通过在硝基苯存在下用硝基烷处理,将Baylis–Hillman加合物的乙酸盐转化为取代的γ-内酰胺,即(E)-5-烷基-3-芳基吡咯烷二-2-酮。描述了碱,然后使用Fe / AcOH进行还原环化。
