An efficient and high-yield preparation of 2-imidazolines was achieved from aldehydes and ethylenediamines in the presence of tert-butyl hypochlorite. By this method, 1,3-bis(imidazolin-2-yl)benzene and 2,6-bis(imidazolin-2-yl)pyridine, which act as chiral ligands, could be prepared directly from the corresponding dialdehydes in high yields.
在次氯酸叔丁酯存在下,由醛和乙二胺高效、高产地制备 2-咪唑啉。通过该方法,可以直接由相应的二醛高收率地制备出作为手性配体的1,3-双(咪唑啉-2-基)苯和2,6-双(咪唑啉-2-基)吡啶。
