Calcium amido-bisoxazoline complexes in asymmetric hydroamination/cyclisation catalysis.

Tracy D Nixon1, Benjamin D Ward.   

Abstract

Calcium complexes bearing bis(oxazolinylphenyl)amine (BOPA) ligands have been prepared, and their redistribution chemistry studied. The complexes [Ca(R-BOPA){N(SiMe(3))(2)}(THF)] (R = (i)Pr 1a, Ph 1b and Bn 1c) are active in hydroamination catalysis and give the highest enantioselectivity reported for a calcium complex.
