We present a modular synthesis of a new class of chiral N,N-chelating ligands containing the C-2-symmetric trans-2,5-disubstituted pyrrolidine moiety linked to a pyridine ring. (-)-2-[(2R,5R)-2,5-Dimethylpyrrolidin-1(ylmethyl]pyridine (11, (R,R)-MePMP), (-)-2-[2-((2R,5R)-2,5-dimethylpyrrolidin-1-yl)ethyl]pyridine (12, (R,R)-MePEP), and (+)-2-[(2R,5R)-2,5-diphenylpyrrolidin-1-ylmethyl]pyridine (13, (R,R)-PhPMP) have been prepared. The X-ray structure of the (eta(3)-allyl)Pd complex of (R,R)-MePMP (11) is reported. (C) 1997 Elsevier Science Ltd.
