Neryl- and geranyltriethylammonium halides in the allylation of sodium diethyl malonate. The effect of the leaving group of the allylating reagent on the selectivity of the reaction

In the absence of catalyst, N-neryl- and N-geranyltriethylammonium halides can allylate sodium ethyl malonate to give terpene malonate derivatives.Using the above-mentioned amonium salts, geranyl and neryl acetates, geranyl ethyl carbonate, and geranyl diethyl phosphate as examples, it has been shown that with Pd0 and PdII catalysts, the selectivity of formation of neryl-, geranyl-, and linalylmalonates can be governed by varying the leaving group of the allylating agent. - Key words: palladium, complexes, catalysis, sodium diethyl malonate, allylation.

In the presence of a catalytic amount of Pd(0), active methylene compounds were allylated by allyl imidates under neutral conditions.In allylation with 3,3-disubstituted allyl imidates, e.g., geranyl and neryl imidate the effect of solvent and ligand to the E/Z ratio are investigated.The reaction in dimethyl sulfoxide by addition of diphosphine, e.g., 1,2-bis(diphenylphosphino)ethane, or large excess of triphenylphosphine as additive ligand gave best results.In these conditions, various active methylene compounds were allylated stereoselectively, especially complete retention of starting olefin geometry was achieved with neryl imidate.
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.
