✦ Synopsis


We present a modular synthesis of a new class of chiral N,Nchelating ligands containing the C2-symmetric trans-2,5-disubstituted pyrrolidine moiety linked to a pyridine ring. (-)-2-[(2R,5R)-2,5-Dimethylpyrrolidin-l-ylmethyl]pyridine (11, (R,R)-MePMP), (-)-2-[2-((2R,5R)-2,5-dimethylpyrrolidin-l-yl)ethyl]pyridine (12, (R,R)-MePEP), and (+)-2-[(2R,5R)-2,5-diphenylpyrrolidin-l-ylmethyl]pyridine (13, (R,R)-PhPMP) have been prepared. The X-ray structure of the (r/3-allyl)Pd complex of (R,R)-MePMP ( ) is reported.
