For example, for 1, the n = 1 series did not show any notable stereoselectivity, whereas the n = 2 series exhibited dramatic diastereoselective enhancements. The ratio of the erythro-isomers 2A and 2A′ is (2.2:1) in THF, and changes to 9:1 when HMPA (2.2 eq) is present. The amounts of threo-isomers 2B and 2B′ was reduced such that the 2AA′:2BB′ ratio changes from 2.7:1 in THF to 10:1 with HMPA (2.2 eq) additive. These effects disappear in the next homologous series n = 3, but are restored when n = 4; 2A:2A′ (4.5:1) (HMPA, 2.2 eq) and 2A/A′:2B/B′ (5.5:1) (HMPA, 2.2 eq). Conditions:-a) THF (0.1M in substrate)/2.2 equiv n-BuLi/0.5h/5.0 equiv PhCHO/-70°C. b) THF (0.1M in substrate)/2.2 equiv n-BuLi/0.5h/2.2 equiv HMPA/0.5K/5.0 equiv PhCHO/-70°C.
