Abstract
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.
Key words
tert-butyl hypochlorite - 2-imidazoline - aldehydes - ethylenediamine
