With the exception of 2-isopropylphenanthroline and 2,9-diisopropylphenanthroline, all 2- and 2,9-substituted phenanthrolines have been previously reported. Neocuproine (2,9-dimethylphenanthroline) was purchased from Aldrich.

It is concluded that diamine (-)-19f has the 2S,9S absolute configuration based on X-ray crystallographic analysis of 21a (Fig. 3).

Apart from steric or strain considerations, the lower yields of 27 and 29 may be a result of competing disproportionation reactions of intermediate dihydrophenanthrolines, as reported for dihydroquinolines. See:

Crystals of rac-32 were used for X-ray determination, as it was not possible to obtain good crystals of (+)-32. The spectroscopic data for rac-32 were identical to optically active (+)-32, confirming that the compounds have the same relative stereochemistry.
