Etude de l'allylation, catalysee par le nickel, d'enolates stables, par les ethers et les alcools allyliques
Alvarez, Eleuterio,Cuvigny, Therese,Julia, Marc
, p. 199 - 212 (2007/10/02)
The allylation of stable enolates derived from diethyl malonate and ethyl cyanoacetate by a variety of aliphatic or aromatic allylic ethers and by allylic alcohols, under nickel catalysis, was investigated.The influence of ligands, solvents and temperature was studied.
SUBSTITUTIONS CATALYSEES AU NICKEL D'ACETATES ET DE SULFONES ALLYLIQUES
Cuvigny, Therese,Julia, Marc
, p. 383 - 408 (2007/10/02)
The allylic substitution of stable enolates derived from diethyl malonate, ethyl cyanoacetate, ethyl benzylsulfonylacetate, bis(benzenesulfonyl)methane and sodium p-toluenesulfinate by a variety of allylic esters and sulfones has been investigated.Suitable ligands and reaction conditions have been found to ensure high yields, and in some cases considerable control of the regioselectivity of the reaction.
ETUDE DE LA REGIOSELECTIVITE DE LA SUBSTITUTION DES CARBANIONS PAR DES DERIVATIVES ALLIQUES CATALYSEE AU PALLADIUM. OBTENTION SELECTIVE DE COMPOSES A CARBONE QUATERNAIRE
Cuvigny, Therese,Julia, Marc,Rolando, C.
, p. 395 - 414 (2007/10/02)
The influence of the leaving groups, carbanions and ligands on ?-allylpalladium has been investigated in the substitution of primary or tertiary terpene derivatives.Conditions have been found under which the substitution takes place essentially at one or the other end of the allylic system.This provides a new and convenient way to obtain compounds with quaternary carbon atoms, which has been exemplified by the synthesis of 3,3-dimethyl-4-pentenenitrile.
ALKYLATIONS ALLYLIQUES CATALYSEES AU NICKEL
Cuvigny, Therese,Julia, Marc
, p. C21 - C24 (2007/10/02)
Stable enolates such as diethyl malonate enolate can be smoothly substituted by allylic acetates (or sulfones) in the presence of nickel complexes.Sulfinate ions convert allylic acetates into sulfones.
