Thirty-seven (most of them novel) chiral derivatives of (1S,4S)-2,5-diazabicyclo[2.2.1]heptane (2–36, 38, 39) were prepared from (S)-trans-4-hydroxyproline. A selection of these chiral ligands were examined as potential ligands in the preparation o

The synthesis of novel chiral ureas (R,R)-2, (S,S)-3 and (R)-6 incorporating the α-phenylethyl group is described. Conformational analysis of these ureas, and of previously reported (R,R)-1, was carried out computationally, both at semiempirical (AM
