Planar chirality remains an underutilized control element in asymmetric catalysis. Factors that have limited its broader application in catalysis include poor catalyst performance and difficulties associated with the economical production of enantiopure planar chiral compounds. The construction of planar chiral azolium salts that incorporate a sterically demanding iron sandwich complex is now reported
平面手性在不对称催化中仍未得到充分利用。限制其在催化领域更广泛应用的因素包括催化剂性能差和与经济生产对映纯平面手性化合物有关的困难。现在报道了结合有空间要求的铁夹心复合物的平面手性偶氮盐的构造。这种新型的N-杂环卡宾既可以用作有机催化剂,又可以用作过渡金属催化的配体,证明了其空前的多功能性和在不对称催化中的广泛用途。
