Cleavage of Esters under Nearly Neutral Conditions at High Pressure. Chemo- and Regioselective Hydrolysis in Organic Solvents

Hydrolysis of esters proceeded at room temperature under high pressure in the presence of iPr2NEt or N-methylmorpholine using CH3CN-H2O (60:1) as the solvent.This very mild procedure enables the smooth hydrolysis of biologically important compounds such as amino esters, aliphatic unsaturated fatty esters, and β-hydroxy esters; no racemization, no isomerization, and no side reactions take place.

3-Methyl 1,1-bis(trimethylsiloxy) 1,3-butadiene et 4-trimethylsilyl 3-methyl 2-butenoate de trimethylsilyle: preparations et reactions avec le benzaldehyde

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.

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

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
