                                    A series of novel C-3 symmetric tris(thiazoline) ligands were synthesized from trimethyl nitrilotriacetate and an enantiomerically pure amino alcohol via an efficient route. Compound 7a showed moderate to good catalytic enantioselectivity for the asymmetric allylic oxidation of cycloalkenes. (C) 2008 Elsevier Ltd. All rights reserved.
