AbstractAnionic adduct derived from malononitrile and heterocumulenes attacks on aziridines or oxiranes in regioselective manner to afford corresponding heterocycles containing highly polarized double bond. This transformation is carried out using Li2CO3 at 25–60 °C in DMF. Graphical abstract

氮丙啶或
环氧乙烷,从而得到含有高极化双键的相应杂环。这种转化是在25-60°C的
DMF中使用Li 2 CO 3进行的。 图形概要
