手性冠醚被用作不对称合成的手性试剂,或者成为具有构型识别能力的主体,它们已成为冠醚化学中的一个引人注目的领域。近年来,也有一些关于含氮手性冠醚的报道,但大多数以氨基酸为基本原料。作者应
Chiral crown ethers have been used as chiral reagents for asymmetric synthesis or have become the mainstay of conformational recognition and have become an attractive area of crown ether chemistry. In recent years, there are some reports about nitrogen-containing chiral crown ethers, but most of them take amino acids as the basic raw material. Author should
