Triethylamine-Catalyzed Efficient Synthesis of Oxathiolanes Containing a Highly Polarized Carbon-Carbon Double Bond from Reaction of Malononitrile, Carbon Disulfide (CS2), and Oxiranes
An efficientsynthesis of functionalized 2‐(1,3‐oxathiolan‐2‐ylidene)malononitrilescontaining a push‐pull CC bond via a simple reaction between malononitrile, CS2, and oxiranes in the presence of Et3N is described (Scheme 1).

AbstractAnionic adduct derived from malononitrile and heterocumulenes attacks on aziridines or oxiranes in regioselective manner to afford corresponding heterocycles containing highly polarized doublebond. This transformation is carried out using Li2CO3 at 25–60 °C in DMF. Graphical abstract
摘要衍生自丙二腈和杂枯烯的阴离子加合物以区域选择性方式攻击氮丙啶或环氧乙烷,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
