Bis(imidazolidine)iodobenzene (I-Bidine) was designed as an organocatalyst based on previously reported imidazolidine- or oxazolidine-containing chiral metal catalysts. I-Bidine showed catalytic activity for the Michael/Henry reaction of thiosalicyl aldehydes with nitroalkenes to give optically active thiochromanes with moderate enantiomeric excesses.
双(咪唑烷)碘苯(I-Bidine)被设计为基于先前报道的含有咪唑烷或恶唑烷的手性金属催化剂的有机催化剂。I-Bidine 对硫代水杨醛与硝基烯烃的 Michael/Henry 反应显示出催化活性,以得到具有适度对映体过量的光学活性硫色满。
