The first series of chiral 2,2':6',2''-terpyridine tri-N-oxide ligands for Lewis base-catalyzed asymmetric allylation of aldehydes.

The first series of chiral 2,2':6',2''-terpyridine tri-N-oxide ligands have been developed; They were showed to be active Lewis base-catalysts for asymmetric allylation of aldehydes using allyltrichlorosilane with optimal results at 0 degrees C for electron-deficient aromatic aldehydes (yields up to 97% and enantioselectivities up to 86% ee).
