4-substituted cyclohexanones (4a∼d) by chiral chelated lithium amides (8a≈k) in the presence of excess trimethylsilyl chloride was realized to give the corresponding chiral silyl enol ethers (6a∼d) in up to 89% ee. It is shown that enantioselectivity of the reaction is dependent on the solvent used, but becomes almost independent on the solvent in the presence of HMPA. The sense of asymmetric induction

The enantioselective aldolreactions of ketone lithium enolates with aldehydes mediated chiral lithium amides were extensively investigated. The chiral amino ethers 4a–4l and diamines 16a,b were prepared from α-amino acids. The reaction conditions and the substituent effects of chiral lithium amides were examined using 4a–4l and 16a,b in the aldolreaction of lithium enolate of 2,2-dimethyl-3-pentanone

Rational Design of Chiral Lithium Amides for Asymmetric Alkylation Reactions-NMR Spectroscopic Studies of Mixed Lithium Amide/Alkyllithium Complexes

Treatment of solutions of chiral lithium amides, containing internally coordinating groups, in diethyl ether (DEE) with alkyllithiums results in the formation of chiral lithium amide/alkyl-lithium mixed dimers. We report the use of eight different chiral lithium amides/n-butyllithium mixed dimers in the asymmetric alkylation of benzaldehyde in DEE solution at -116 degrees C. The addition product, (S)-1-phenyl-1-pentanol, was formed with enantiomeric excesses (ee's) ranging from 0 to 82%. In DEE/dimethoxy methane solvent mixtures the stereoselectivity was improved and gave the product in 91% ee. Comparison of the ligand structures revealed that only one chiral center was necessary to obtain high enantioselectivity. Replacement of the internally coordinating methoxy group with a pyrrolidine group lowered the ee from 82% to 24%, Low-temperature Li-6 NMR studies of mixtures of these reagents in DEE revealed large differences in the concentration of the reactive mixed dimers formed. Full complexation of nBuLi to the chiral lithium amides is not necessary in order to obtain high enantioselectivity, as the result of an increased reactivity of the complexed nBuLi.
