Three-component, room temperature crotylation catalyzed by solid-supported Brønsted acid: enantioselective synthesis of homoallylic carbamates.
[reaction: see text] A heterogeneous, three-component crotylation of in situ generated N-acyl iminium ions has been developed. This reaction proceeds under ambient temperature in MeCN and is catalyzed by macroporous polystyrene-bound sulfonic acid (MP-TsOH). Workup is accomplished by filtration, upon which the catalyst is recoverable. A range of homoallylic amine equivalents have been prepared ...
متن کاملEfficient and eco-friendly synthesis of quinoxalines derivatives catalyzed by acidic ionic liquids at room temperature
In this research, we have developed cheap recyclable and task-specific acidic ionic liquids (AILs) 1-hydrogen-3-methylimidazolium hydrogen sulfate [Hmim]HSO4, 1-hydrogen-3-methylimidazolium chloride [Hmim]Cl, 2-pyrrolidonium hydrogensulfate [Hnhp]HSO4 and applied them in acid catalyzed synthesis of quinoxaline derivatives from 1,2-phenylendiamines and 1,2-dicarbonyl compounds. The products coul...

متن کاملNickel-catalyzed synthesis of aryl trifluoromethyl sulfides at room temperature.
Inexpensive nickel-bipyridine complexes were found to be active for the trifluoromethylthiolation of aryl iodides and aryl bromides at room temperature using the convenient [NMe(4)][SCF(3)] reagent.
متن کاملImidazole Functionalized Magnetic Fe3O4 Nanoparticles a Highly Efficient and Reusable Brønsted Acid Catalyst for the Regioselective Thiocyanation of Aromatic and Heteroaromatic Compounds at Room Temperature in Water:Ethanol
The Magnetically recoverable Fe3O4 nanoparticle and the supported brønsted acidic ionic liquid 1-methyl-3-(3-trimethoxysilylpropyl) imidazolium hydrogen sulfate (Fe3O4-IL-HSO4) were synthesized and used as efficient magnetic catalysts for the regioselective thiocyanation of aromatic and heteroaromatic compounds at room temperature in Water: Ethanol. This procedure provided the target thiocyanat...
