New C-substituted derivatives of (1S,4S)-2-methyl-2,5-diazabicyclo[2.2.1]he
ptane were synthesized utilizing the directed metalation strategy. The abso
lute configuration of the 3-substituted derivative rests on the comparison
of the NMR spectra with a product of proven configurational assignment by X
-ray crystallographic analysis.
