Synthesis of a New Chiral Ligand Containing 1, 5-Diazacyclooctane and the Application in Diethyl Zinc Addition to Benzaldehyde

摘要

A new chiral tetradentate ligand (S, S)-1, 5-bis (4-benzyloxazolin-2-yl-methyl)-1, 5-diazacyclo-octane 1 has been synthesized and the application of 1 as catalyst in the enantioselective addition of diethyl zinc to benzaldehyde is also described.
