The asymmetric alkynylation reaction catalyzed by amino alcohol derived ligands (1R,2S)-3 or (1S,2R)-4 with dimethylzinc provides a simple and practical method to make chiral propargylic alcohols, and it is complementary to the asymmetric reduction methods. In the presence of 10 mol% (1R,2S)-3 or (1S,2R)4, a variety of aromatic aldehydes were converted to the corresponding chiral propargylic alcohols with very good enantioselectivities and yields. This one-pot asymmetric reaction is carried out under mild reaction conditions. Neither strong base nor transmetallation is required. It is an efficient reaction, greatly accelerated by the added chiral ligand. Preliminary mechanistic and NMR studies have also been carried out.

A new chiral tetraphenylethylene derivative with the AIE effect was synthesized and showed not only high enantioselectivity for a wide range of chiral acids but also a high sensitivity of 3.0 × 10-6 M scale. The enantiomeric purity of chiral acids could be quantitatively determined by this chiral sensor.

(matrix presented) Amino alcohol 4 (or its enantiomer) is prepared in two simple steps. Commercial (1R,2S)-2-amino-1,2-diphenylethanol is dialkylated with bis(2-bromoethyl) ether. Subsequent hydrogenation over 5% Rh on alumina in the presence of morpholine unexpectedly stops at the hexahydro derivative 4. Amino alcohol 4 promotes the enantioselective addition of diethylzinc to aldehydes at room temperature in up to 99% enantiomeric excess.

Treatment of 4-, 3- or 2-aryl-4,5-diphenyloxazolines with isopropyllithium gives the products of dearomatising addition, fluorine-directed lithiation or nucleophilic aromatic substitution of fluoride depending on substitution pattern and conditions. In the case of the 4-fluoroaryl substrates, fluorinated 1,4-cyclohexadiene may be obtained in good yield.

The first enantioselective epoxidation of readily available alkylidenemalononitriles has been developed by using a multifunctional cinchona derived thiourea as the organocatalyst and cumyl hydroperoxide as the oxidant. A new simple one-pot asymmetric epoxidation/SN2 ring-opening reaction with 1,2-diamines leading to important enantioenriched heterocycles, i.e. 3-substituted piperazin-2-ones, has been established.

The title compounds were prepared by condensation of isophthaldehyde with chiral amino alcohols or alpha-amino esters in three different ways depending on the substitution pattern. These methods are: for N-substituted amino alcohols, by reduction of the epimeric mixtures of 1,3-oxazolidines formed in the condensation process; for unsubstituted ones, by reduction of the corresponding hydroxy imines, followed by N-alkylation; and for the imines obtained in the condensation with amino esters, by sequential reduction and reaction with methylmagnesium iodide.

Novel organic molecules containing an l-proline amide moiety and a terminal hydroxyl for catalyzing direct asymmetric aldol reactions of aldehydes in neat acetone are designed and prepared. Catalyst 3d, prepared from l-proline and (1S,2S)-diphenyl-2-aminoethanol, exhibits high enantioselectivities of up to 93% ee for aromatic aldehydes and up to >99% ee for aliphatic aldehydes. A theoretical study of transition structures demonstrates the important role of the terminal hydroxyl group in the catalyst in the stereodiscrimination. Our results suggest a new strategy in the design of new organic catalysts for direct asymmetric aldol reactions and related transformations because plentiful chiral resources containing multi-hydrogen bond donors, for example, peptides, might be adopted in the design.

A ruthenium complex formed from commercially available [Ru(p-cymene)Cl 2]2 and 1,4-bis(diphenylphosphino)butane catalyzes the racemization of aromatic alpha-hydroxy ketones very efficiently at room temperature. The racemization is fully compatible with a kinetic resolution catalyzed by a lipase from Pseudomonas stutzeri. This is the first example of dynamic kinetic resolution of alpha-hydroxy ketones at ambient temperature in which the metal and enzyme catalysts work in concert in one pot at room temperature to give quantitative yields of esters of alpha-hydroxy ketones with very high enantioselectivity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C14H15NO, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 23364-44-5, in my other articles.

A highly efficient dinuclear copper complex catalyzed Friedel-Crafts reaction has been demonstrated for the alkylation of 1-naphthol using N-tosyl aldimine. In this context, various chiral amino alcohol derived Schiff base ligands with different achiral and chiral linkers were synthesized and their copper (II) complexes were generated in situ. One of the dinuclear copper complexes with chiral linker has emerged as an efficient catalyst and affords the desired arene products in excellent enantioselectivities (ee up to 99%) with very good yields (up to 98%). The dinuclear catalyst used in this study was recoverable and recyclable with retention of its catalytic activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 23364-44-5, you can also check out more blogs about23364-44-5
