Curcumin inspired synthesis of unsymmetrical diarylpentanoids with highly potent anti-parasitic activities:: In silico studies and DFT-based stereochemical calculation

Unsymmetrical diarylpentanoid analogues of curcumin have been synthesized by Claisen-Schmidt condensation of different aldehydes and ketones. Anisaldehyde treated with 2-butanone and chlorobenzaldehyde with 2-pentanone resulted in intermediate compounds 1

Hydroperoxidations of Alkenes using Cobalt Picolinate Catalysts

Hydroperoxides were synthesized in one step from various alkenes using Co(pic)2as the catalyst with molecular oxygen and tetramethyldisiloxane (TMDSO). The hydration product could be obtained using a modified catalyst, Co(3-mepic)2, with molecular oxygen and phenylsilane. Formation of hydroperoxides occurred through a rapid Co-O bond metathesis of a peroxycobalt compound with isopropanol.

Decarboxylation-triggered homo-Nazarov cyclization of cyclic enol carbonates catalyzed by rhenium complex

Decarboxylative homo-Nazarov cyclization catalyzed by a Lewis acid was achieved using a cyclic enol carbonate bearing a cyclopropane moiety as a substrate. Various substrates were converted into the corresponding multi-substituted cyclohexenones in good yieldsviadecarboxylation, followed by 6-membered ring formation involving cyclopropane-ring-opening.

Highly Enantioselective Iridium-Catalyzed Hydrogenation of Conjugated Trisubstituted Enones

Asymmetric hydrogenation of conjugated enones is one of the most efficient and straightforward methods to prepare optically active ketones. In this study, chiral bidentate Ir-N,P complexes were utilized to access these scaffolds for ketones bearing the stereogenic center at both the α- and β-positions. Excellent enantiomeric excesses, of up to 99%, were obtained, accompanied with good to high isolated yields. Challenging dialkyl substituted substrates, which are difficult to hydrogenate with satisfactory chiral induction, were hydrogenated in a highly enantioselective fashion.

Thermal decarboxylative Nazarov cyclization of cyclic enol carbonates involving chirality transfer

Decarboxylative Nazarov cyclization of chiral cyclic enol carbonates proceeded to afford chiral 2-cyclopentenones with excellent chirality transfer under thermal conditions without any catalyst. Interestingly, the thermal decarboxylative Nazarov cyclization furnished the desired product with better chirality transfer than the Lewis acid-catalyzed reaction.

RhIII-Catalyzed Synthesis of Highly Substituted 2-Pyridones using Fluorinated Diazomalonate

A RhIII-catalyzed strategy was developed for the rapid construction of highly substituted 2-pyridone scaffolds using α,β-unsaturated oximes and fluorinated diazomalonate. The reaction proceeds through direct, site-selective alkylation based on migratory insertion and subsequent cyclocondensation. A wide substrate scope with different functional groups was explored. The requirement of fluorinated diazomalonate was explored for this transformation. The developed methodology was further extended with the synthesis of the bioactive compound.

Organoseleno-catalyzed synthesis of α,β-unsaturated α′-Alkoxy ketones from allenes enabled by se···o interactions

α,β-Unsaturated α′-Alkoxy ketones have been prepared under mild conditions from allenes using water as the oxygen source and without the necessity of metals. The organocatalytic oxygenation-rearrangement sequence displays an exquisite chemo-, stereo-, and

Synthesis, characterization, molecular docking evaluation, antidepressant, and anti-Alzheimer effects of dibenzylidene ketone derivatives

Novel bioactive compounds as synthetic analogs of the potent herbal medicines can be optimized as potential drug candidates for various neurologic disorders. This study was performed to investigate the newly synthesized dibenzylidene ketone derivatives: (2E,6E)-2,6-dibenzylidene cyclohexanone (A1K1) and (1E,4E)-5-(2,3-dichlorophenyl)-1-(4-methoxyphenyl)-2-methylpenta-1,4-diene-3-one (A2K2) and evaluate its potential anti-Alzheimer's and anti-depressant properties. Both the derivatives are chemically characterized by using HNMR and CNMR techniques. Auto Dock Vina program was used to investigate ligand-protein affinity. Forced swim test, tail suspension test, open field test, Y-maze test, and Morris water maze test (MWM) models were employed to evaluate anti-depressant and anti-Alzheimer's activity of dibenzylidene ketone derivatives in mice. Both A1K1 and A2K2 showed high binding affinities against various proteins involved in depression and Alzheimer's mechanisms like monoamine oxidase B, acetylcholinesterase, norepinephrine transporter 2, serotonin transporter, dopamine receptor, serotonin receptor modulator, and beta-amyloid targets. A1K1 and A2K2 dose-dependently (0.1–1 mg/kg) decreased immobility time, while increased swimming and climbing time of mice in forced swim test (FST). A1K1 and A2K2 decreased animal immobility time in TST. In the open field test, both A1K1 and A2K2 increased the number of ambulations and rearings. A1K1 and A2K2 dose-dependently (0.5–1.0 mg/kg) increased spontaneous alternation behavior (%) and the number of entries of mice in Y-maze test. In the MWM test, A1K1 and A2K2 decreased escape latency time. Overall, both in-silico and in-vivo investigations of A1K1 and A2K2, report their therapeutic potential for antidepressant and anti-Alzheimer properties. Hence, these compounds possess potent neuroprotective properties and may be further evaluated for their therapeutic potential in various neurological disorders.

Stereodivergent Evolution of Artificial Enzymes for the Michael Reaction

Enzymes are valuable biocatalysts for asymmetric synthesis due to their exacting stereocontrol. Changing the selectivity of an existing catalyst for new applications is, however, challenging. Here we show that, in contrast, the stereoselectivity of an art

Extractive biocatalysis in the asymmetric reduction of α-alkyl, β-aryl enones by Baker's yeast

We prepared various chiral α-alkyl, β-aryl ketones with good to excellent enantiomeric excess through the Baker's yeast asymmetric double-bond reduction of the corresponding α,β-unsaturated substrates adsorbed onto the resin Amberlite XAD-7. This methodology was compatible with substrates bearing both electron-donating and withdrawing groups attached to the aromatic ring. Elongation of the α-alkyl substituent of the starting material strongly affected the reactivity and enantioselectivity of the reaction.
