Asymmetric, catalytic, and direct self-aldol reaction of acetaldehyde catalyzed by diarylprolinol

(Chemical Equation Presented) An asymmetric, catalytic, and direct self-aldol reaction of acetaldehyde was catalyzed by diarylprolinol in NMP, affording the trimer acetal, which was generated by the reaction of the self-aldol product with another acetaldehyde molecule in a moderate yield with good enantioselectivity. Acetal is the synthetic equivalent of the self-aldol product, which can be converted into other synthetically useful compounds in one pot without compromising the enantioselectivity.

Catalytic asymmetric chloroamination reaction of alpha,beta-Unsaturated gamma-keto esters and chalcones

Highly efficient catalytic chloroamination reaction of alpha,beta- unsaturated gamma-keto esters and chalcones has been developed via a chloronium-based mechanism to deliver anti-regioselective vicinal chloroamines instead of the aziridinium intermediates delivered aminochlorides. The combination of TsNCl2 and TsNH2 as reagents made the transformation highly efficient, delivering the gamma-carbonyl-beta-chloro- alpha-amino acid derivatives and alpha-chloro-beta-amino-ketone derivatives in nearly quantitative yields with up to 99% ee and 99:1 dr under 0.05-0.5 mol % catalyst loading. TsNHCl was demonstrated to act as the key reactive species to form a bridged chloronium ion intermediate in the presence of a chiral scandium complex. The method might provide useful information for further realization of other haloamination reactions.

Palladium nanoparticles supported on magnesium hydroxide fluorides: A selective catalyst for olefin hydrogenation

A one-pot synthesis of palladium nanoparticles supported on magnesium hydroxide fluoride has been performed with the fluorolytic sol-gel method. The prepared catalysts were characterized by using various physicochemical techniques. The sol-gel method led to high surface area (> 135 m2g-1), mesoporous catalysts (pore volume=0.19-0.23 cm3g-1, pore diameter= 3-5 nm) with uniformly dispersed palladium nanoparticles approximately 2 nm in diameter on the surface. The catalysts synthesized by using different concentrations of aqueous hydrofluoric acid exhibited changing surface and acidic properties. Very high dispersion of palladium on magnesium fluoride (47%) was obtained with 1 wt% palladium loading. The catalysts were used for hydrogenation of various olefins in the presence of other organic functionalities at room temperature and atmospheric hydrogen pressure. Various substituted olefins were hydrogenated with almost 100% conversion and selectivity. The catalysts were recycled efficiently over five cycles without appreciable loss in catalytic activity. There was no palladium leaching under the reaction conditions, which was confirmed by inductively coupled plasma atomic emission spectroscopy analysis. Activation of olefin on the catalyst surface could not be observed by in situ FTIR studies, indicating facile activation of hydrogen on the palladium supported on magnesium hydroxide fluoride.

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 In Synthesis of 1,5-Diphenylpenta-1,4-dien-3-one, you can also check out more blogs about538-58-9

Efficient general synthesis of 1,2- and 1,3-Diols in high enantiomeric excess via the intramolecular asymmetric reduction of the corresponding ketoalkyl diisopinocampheylborinate intermediates

The first successful asymmetric reduction of unhindered aliphatic ketones with B-chlorodiisopinocampheylborane is reported. In contrast to the reduction in high ee of aralkyl ketones, such as acetophenone, with the reagent, the reduction of unhindered dialkyl ketones, such as 3-methyl-2-butanone, provides only poor ee. However, treatment of alpha- and beta-hydroxyketones with one equiv of diisopnocampheylborane or B-chlorodiisopinocampheylborane rapidly produces the corresponding ketoalkyl diisopinocampheylborinate intermediates, which then undergo facile intramolecular reduction. This reaction sequence, followed by oxidative workup, provides a general synthesis of 1,2- and 1,3-diols in 84?99% enantiomeric excess.
