Sažetak

By means of selective deuterium labeling combined with separation of enantiomers, chiral discrimination
in the proton-bound dimers of 1-aza[6]helicene is probed by electrospray mass spectrometry. The analysis of the results reveals a pronounced preference for the formation of homochiral dimers (P,P
and M,M) over the heterochiral variant (P,M).
