UNEXPECTED AFFECTS OF Me3Si-X ON REACTIONS OF HIGHER ORDER CYANOCUPRATES
Lipshutz, Bruce H.,Ellsworth, Edmund L.,Siahaan, Teruna J.,Shirazi, Ata
, p. 6677 - 6680 (1988)
The assumed compatibility of Me3SiCl with higher orger cyanocuprates has been studied by both chemical and spectroscopic (1H, 7Li, 29Si NMR) means.Both types of experiments confirm that Me3Si-X significantly alters the composition of both homo (R2Cu(CN)Li
Stereoselective addition of organomanganese reagents to chiral acylsilanes and aldehydes
Boucley, Céline,Cahiez, Gérard,Carini, Silvia,Cerè, Vanda,Comes-Franchini, Mauro,Knochel, Paul,Pollicino, Salvatore,Ricci, Alfredo
, p. 223 - 228 (2007/10/03)
Organomanganese halides and organomanganates prepared by transmetalation of organolithium and Grignard reagents add smoothly to the carbonyl moiety of acylsilanes and of substituted aldehydes bearing a chiral center at the α-position affording the desired

Ligand effects on diastereoselective addition of organocerium reagents to aldehydes and cyclic ketones
Greeves, Nicholas,Lyford, Lisa,Elizabeth Pease
, p. 285 - 288 (2007/10/02)
A new class of chiral dialkoxy- and diaryloxyorganocerium reagent has been prepared and the diastereoselectivity of carbonyl addition reactions has been compared with that of conventional organocerium reagents.
Highly Diastereoselective 1,2-Asymmetric Addition of Dialkylzincs to Chiral 2-Phenylpropanal Catalyzed by Amino Alcohol
Soai, Kenso,Niwa, Seiji,Hatanaka, Toshihiro
, p. 2129 - 2130 (2007/10/02)
Diastereoselective addition of dialkylzinc reagents to 2-phenylpropanal using amino alcohol as catalyst afforded erythro alcohols (Cram-selectivity) in high diastereomeric excess (up to 88percent d.e.).
Me3SiCl-ASSISTED 1,2-ADDITION OF ORGANOCUPRATES TO CARBONYL COMPOUNDS
Matsuzawa, Satoshi,Isaka, Masahiko,Nakamura, Eiichi,Kuwajima, Isao
, p. 1975 - 1978 (2007/10/02)
Me3SiCl not only accelerates the 1,2-additions of organocopper reagents to carbonyl compounds, but also enhances the Cram diastereoselectivity of the addition to a chiral aldehyde.
