This result also suggests that ligand exchange catalysis (see ref. 25) is occurring to some extent, with the less reactive s-BuLi/(-)-sparteine as the regenerating system

This reactivity order should be treated as a guide for use in synthesis as it assumes that essentially all of each diamine is complexed to the s-BuLi

A similar reactivity difference between s-BuLi/TMEDA and s-BuLi/(-)-sparteine was noted in the lithiation of a N-Boc bispidine:

Er determined by chiral HPLC on the p-bromobenzamide of 12 or by chiral GC. Absolute configuration assigned by analogy with the (R)-N-Boc stannane which was transformed into the known (R)-N-Me stannane. For the (S)-N-Me stannane, see:
