Reactions conducted on a 0.1 mmol scale using 1.2 equiv of 1, 2.5 equiv of LiN(SiMe3)2, 5 equiv of 12-crown-4, and 1 equiv of 2 at 0.1 M. Isolated yield after chromatographic purification.
1a:LiN-(SiMe3)2:12-crown-4:2 = 2:1.5:3:1.
1a:LiN(SiMe3)2:12-crown-4:2 = 2:2:4:1.
1a:LiN(SiMe3)2:12-crown-4:2 = 1:2:4:2.
1a:LiN-(SiMe3)2:12-crown-4:2 = 1.2:3:6:1.
NaOtBu was used as base.
CPME was used as solvent.
