摘要:Disclosed is the use of an N-heterocyclic carbene-based compounded nickel (II) complex in the synthesis of an α-benzyl benzofuran compound. In the present invention, an air-stable compounded nickel (II) complex Ni[P(OEt) 3 ]{[R`NC(CH 3 )C(CH 3 )NR`]C}Br 2 is used as a catalyst, wherein R` is 2,4,6-trimethylphenyl, and the α-benzyl benzofuran compound is synthesized by means of a hydrogen heteroarylation reaction of an aryl ethylene compound and a benzofuran compound in the presence of an organic base. The operability and substrate applicability of the catalyst are obviously better than those of the prior art, and meanwhile, the nickel catalyst has a higher practical application value due to the air stability and easiness of synthesis thereof.

摘要:The present invention relates to a multifunctional reusable catalyst and to a process for the preparation thereof on a single matrix of the support to perform multicomponent reaction in a single pot. The multifunctional catalysts of the invention are useful for the synthesis of chiral vicinal diols by tandem and/or simultaneous reactions involving Heck coupling, N-oxidation and AD reaction of olefins in presence of cinchona alkaloid compounds both as an native one and immobilized one in the said matrix support. This invention also relates to a process for preparing vicinal diols by asymmetric dihydroxylation of olefins in presence of cinchona alkaloid compounds employing reusable multifunctional catalysts as heterogeneous catalysts in place of soluble osmium catalysts.

摘要:The subject invention provides catalytical compounds/complexes, compositions comprising such compound/complex, synthesis of the compounds/complexes, and methods of using such compounds/complexes as catalysts in, for example, carbon isotope exchange (CIE) on target bioactive molecules. Methods that allow CIE directly on drug candidates are of great importance to chemistry, biology, and medicine. Especially valuable are catalytic procedures that rely on a limited collection of available labeled materials. The instant method comprises converting a methyl group to terminal â•?CH2 utilizing transfer dehydrogenation catalysts to enable V-based olefin metathesis, followed by a hydrogenation step. The one-pot strategy allows the formal methylation/demethylation sequence and can be applied to an assortment of alkyl-containing compounds.
