Lithiation of l',2',3',4',5'-pentamethyl-3,4-diphenylazaferrocene (9) with sec-BuLi/(-)-sparteine (2) in Et 2 O at -78 °C followed by quenching with electrophiles gave the C-2 functionalized azaferrocenes (17) in good enantioselectivities (up to 79% ee). In contrast, treatment of 9 with tert-BuLi/(-)-sparteine (2) leaded to lateral lithiation at the methyl group of cyclopentadienyl ring.
