Rapid access to homoallylic alcohols via Pd(OAc)2 catalyzed Barbier type allylation in presence of DMAP

DMAP was found to accelerate significantly the rate of Pd(OAc)2 catalyzed Barbier type allylation of carbonyl compounds by allylbromide using SnCl2·2H2O as reducing agent. Both aldehyde as well as ketones produced excellent yields within a short reaction time in the presence of 3 mol % of Pd(OAc)2 and 12 mol % of DMAP at room temperature. Aldehydes could be allylated within 5-10 min whereas, in case of ketones, the reaction completes in 45-120 min.

[bmim][Br] as an Inexpensive and Efficient Medium for the Barbier-Type Allylation Reaction Using a Catalytic Amount of Indium: Mechanistic Studies

Barbier-type allylation reactions of aldehydes and ketones have been carried out with both unsubstituted and γ-substituted allyl bromides using only a catalytic amount (0.1 equiv.) of In metal in [bmim][Br], but not in H2O, organic solvents, or

Efficient synthesis of homoallylic alcohols/amines from allyltributylstannane and carbonyl compounds/imines using iodine as catalyst under acetic acid-water medium

This paper describes a general method for the synthesis of homoallylic alcohols and amines by nucleophilic addition reaction of allyltributylstannane to carbonyl compounds and aldimines where iodine acts as a catalyst in H2O/acetic acid (1:1) medium. Only 10 mol% of I2 is required for various organic transformations. By using this process, various homoallylic alcohols and amines are produced in good to excellent yields.

Hydroxyl group-assisted palladium-catalyzed lactonization of homoallylic alcohols

A convenient and highly efficient synthesis of α-methylene-γ- lactones through the palladium(II)-catalyzed lactonization of homoallylic alcohols with alkynamides has been reported. The hydroxyl group in the terminal olefins cooperates with the amide in alkynamides to promote the cyclization by suppressing the β-H elimination. This process provides a route to construct naturally occurring biologically multifunctional α-methylene-γ- lactones.

SnCl2·2H2O-mediated Barbier-type allylation: A comparative evaluation of the catalytic performance of CuI and Pd(OAc) 2

A systematic investigation has been carried out for the allylation of carbonyl compounds under SnCl2·2H2O-mediated Barbier-type conditions, using CuI and Pd(OAc)2 as catalysts. Ketones, which are not reactive under the influence of CuI, however, could be activated by using Pd(OAc)2 as a catalyst.

Allylation of cyclohexanones in aqueous media and influence of facial amphiphilic fructopyranosides

The indium-catalyzed allylation reaction was performed in good yields and short reaction time with various cyclohexanones in water. Aqueous facial amphiphilic carbohydrates solutions were also screened for their potency to modify the stereochemical outcom
