2-Alkyl-2-cyanocycloalkanones 4 bearing a quaternary stereogenic center are synthesized in good overall yields and high enantiomeric excesses (ee = 90-95%) employing the SAMP-/RAMP-hydrazone method. The absolute configuration is confirmed by NMR-spectroscopic investigations on SAMP-hydrazone 3a and an X-ray structure analysis of SAMP-hydrazone 3f.
