reagent has been prepared and used effectively in a variety of one‐pot Wittig reactions. The design of this reagent resolved a deficiency of a previously reported related material, and allowed it to perform more efficiently in such reactions. Furthermore, it was readily recyclable, and was also successfully applied in cascade processes involving one‐pot Wittig reactions followed by either a conjugate
已经制备了一种新的三芳基膦-叔胺双功能聚合试剂,并已有效地用于各种单罐Wittig反应中。该试剂的设计解决了先前报道的相关材料的不足,并使其在此类反应中可以更有效地发挥作用。此外,它易于回收利用,并且还成功地用于级联过程中,涉及一锅Wittig反应,然后进行共轭还原或还原性醇醛缩合反应。在这些反应级联中,在维蒂希反应中产生的氧化膦基团用作随后反应的催化剂。
