Asymmetrische Katalysen, 116. Triaza-und Tetraaza-Makrocyclen mit chiralen "pendant arms" in der enantio- selektiven Cyclopropanierung / Asymmetrie Catalyses, 116. Triaza and Tetraaza Macrocycles with Chiral Pendant Arms in the Enantioselective Cyclopropanation

The chiral ligands 1 - 5 were tested in the Cu1- catalyzed enantioselective cyclopropanation of styrene with ethyl diazoacetate. The new ligand 5 was synthesized by reaction of 1,4,8,11-tetraazacyclotetradecane (cyclam ) with (S)-propylene oxide and characterized by X-ray analysis.
