Novel C2 chiral diamine ligands derived from cyclic Tröger bases
摘要:
The endomethylene bridge in a macrocyclic Troger base was removed efficiently to provide a dibenzodiazocine derivative, and its N-methyl and N,N'-dimethyl derivatives. These Ct chiral diamines could be separated into their optical antipodes by HPLC using a chiral column. Complex formation of these new type ligands with several metal salts was also examined.
