SUR LA REGIO SELECTIVITE DE LA REACTION DU BENZALDEHYDE AVEC LES ORGANOZINQUES ISSUS DU γ-BROMOCROTONATE ET DU γ-BROMOSENECIOATE DE TRIMETHYLSILYLE
Bellassoued, M.,Gaudemar, M.,Borgi, A. El.,Baccar, B.
, p. 165 - 172 (1985)
The regioselectivity of the reaction of organozinc compounds derived from γ-bromocrotonic and γ-bromosenecioic trimethylsilyl esters, with benzaldehyde is discussed.One-step reactions lead to a majority of α-substituted derivatives, while in two-step reactions, γ-substituted products are exclusively obtained.
3-Methyl 1,1-bis(trimethylsiloxy) 1,3-butadiene et 4-trimethylsilyl 3-methyl 2-butenoate de trimethylsilyle: preparations et reactions avec le benzaldehyde
Bellassoued, M.,Ennigrou, R.,Gaudemar, M.
, p. 19 - 25 (2007/10/02)
The regioselectivity of the reaction between benzaldehyde and the silylketene acetal prepared from trimethylsilylsenecioate is studied as a function of the catalyst used.CsF leads exclusively to the "branched" product whereas TiCl4 gives the required "lin
SUR LA REACTION DE REFORMATSKY. II-PREPARATION ET REACTIVITE DE L'ORGANOZINCIQUE ISSUS DU SEL BROMOZINCIQUE DE L'ACIDE γ-BROMOSENECIOIQUE.
Bellassoued, M.,Habbachi, F.,Caudemar, M.
, p. 1785 - 1792 (2007/10/02)
The condensation of benzaldehyde and cyclohexanone with the bromozinc salt derived from γ-bromosenecioic acid, in the presence of zinc, yield unsaturated hydroxyacids or lactones.The equilibration of the intermediary alcoxides is studied.
SUR LA REGIO SPECIFICITE DE LA REACTION DE REFORMATSKY APPLIQUEE AU γ-BROMOCROTONATE ET AU γ-BROMOSENECIOATE DE TRIMETHYLSILYLE
Bellassoued, M.,Dardoize, F.,Frangin, Y.,Gaudemar, M.
, p. C1 - C4 (2007/10/02)
The regiospecificity of Reformatsky reactions of γ-bromocrotonic and γ-bromosenecioic timethylsilyl esters are discussed.One-step reactions lead to a majority of α-substituted derivatives, while in two-step reactions, the γ-substituted products are obtain
