Conjugate addition of diorganozincs to α,β-unsaturated ketones catalyzed by a copper(I)-sulfonamide combined system
Kitamura, Masato,Miki, Takashi,Nakano, Keiji,Noyori, Ryoji
, p. 5141 - 5144 (1996)
In the presence of a Cu(I)-N-monosubstituted sulfonamide combined catalyst system, diorganozincs react with α,β-unsaturated ketones to generate Zn enolates, which may be hydrolyzed, giving the β-substituted ketones, or used for further aldol reaction or Pd(O)-catalyzed reaction with allyl acetate leading to the regiospecific α,β-vicinal condensation products.
STEREOCHEMISTRY OF THE C3 ADDITION OF 1-LITHIO 1,1-BIS METHYLSELENOALKANES TO METHYL CYCLOHEXENONES
Lucchetti, J.,Krief, A.
, p. 1623 - 1626 (2007/10/02)
The presence of DME or HMPT allows the C3 regio and stereoselective introduction of 1,1-bis methylselenoalkanes to methyl cyclohexenones.The resulting compounds have been stereoselectively transformed to 3-ethyl methyl cyclohexanones.
