Enantiopure N,N′-bidentate ligands (N,N′)*, containing substituted aziridine and aza-aromatic rings, were prepared from imines derived from (S)-valinol or (R)-phenylglycinol and heteroaromatic aldehydes (2-pyridine-, 6-benzyl-2-pyridine-, 2- and 8-quinoli

(Chemical Equation Presented) The enantioselective allylic amination of acyclic allylic carbonates catalyzed by a palladium/(S)-BINAP(S) system was investigated. Amination of several substrates proceeded with high ee. Crotyl carbonates show an unusually high regioselectivity for the branched isomer. The use of (S)-TolBINAP(S) and (S)-3,5-xylyl-BINAP(S) as ligands was found to increase the enantioselectivity of the aminations. A P,S binding mode of the BINAP(S) ligand was found in an X-ray crystallographic study.
