Palladium-Catalyzed Aminomethylation of Nitrodienes and Dienones via Double C—N Bond Activation

A new strategy for the generation of the active Pd-alkyl species from aminal via C—N bond activation has been established, in which the formation of zwitterionic intermediate through aza-Michael addition of aminal to nitrodienes or dienones is identified as a key step for the activation of the C—N bond. The efficient strategy has enabled a new palladium-catalyzed α-aminomethylation of nitrodienes and dienones via double C—N bond activation. The scope and versatility of the reaction were demonstrated and a broad range of substrates bearing electron-donating and -withdrawing groups on the aromatic rings were all compatible with this reaction to furnish the desired α-aminomethylated products in moderate to good yields with excellent regioselectivities and E/Z selectivities.

Antibacterial & antitubercular activities of cinnamylideneacetophenones

Cinnamaldehyde is a natural product with broad spectrum of antibacterial activity. In this work, it was used as a template for design and synthesis of a series of 17 cinnamylideneacetophenones. Phenolic compounds 3 and 4 exhibited MIC (minimum inhibitory

Highly regioselective introduction of aryl substituents via asymmetric 1,4-addition of boronic acids to linear α,β,γ,δ-unsaturated ketones

An efficient palladium(II)-catalyzed regioselective asymmetric 1,4-conjugate addition of arylboronic acids to linear α,β,γ,δ-unsaturated ketones is developed using phosphapalladacycle catalysts. The relevant 1,4-products were obtained exclusively with per

Asymmetric 1,4-Conjugate Addition of Diarylphosphines to α,β,γ,δ-Unsaturated Ketones Catalyzed by Transition-Metal Pincer Complexes

An enantioselective asymmetric 1,4-addition of diarylphosphines to linear α,β,γ,δ-unsaturated dienones was developed. A series of chiral PCP- and PCN-transition-metal (Pd, Pt and Ni) pincers, themselves prepared catalytically via asymmetric hydrophosphination, were sequentially screened to reveal the roles of backbone architecture and metal ion in catalyst design. The selected ester-functionalized PCP-palladium pincer afforded the chiral 1,4-phosphine adducts in excellent yields with up to >99% ee. The same catalyst when utilized for the hydrophosphination of an α,β,γ,δ-unsaturated malonate ester also revealed the critical role played by the ester functionality on the ligand backbone in dictating the enantioselectivity of the 1,6-adduct.

Synthesis, antimicrobial and cytotoxic activity of novel 1,5 benzodiazepine derivatives

In the present study, a series of novel 2-(substituted phenyl)-3-styryl-2,3-dihydro- 1H-benzo [b] [1,4] diazepines (1-12) has been synthesized from 1,5-(disubstituted phenyl)-2,4-pentadien-1-ones (1a-12a). 1,5-(disubstituted phenyl)-2,4-pentadien-1-ones were prepared by condensing cinnamaldehyde with various aromatic ketones in the presence of 20% NaOH as base. Different 1,5-(disubstituted phenyl)-2,4-pentadien-1-ones on cyclisation with o-phenylene diamine in the presence of NaOH as base resulted in 2-(substituted phenyl)-3-styryl-2,3-dihydro-1H-benzo [b] [1,4] diazepine derivatives. The structures of the newly synthesized compounds were characterized by elemental analysis, IR, 1H NMR and mass spectroscopic studies. All titled compounds were screened for their antimicrobial and cytotoxic activities. Most of the compounds showed promising cytotoxic, antibacterial and antifungal activities.

Further studies on anti-invasive chemotypes: An excursion from chalcones to curcuminoids

In our ongoing search for new anti-invasive chemotypes, we have made an excursion from previously reported potent 1,3-diarylpropenones (chalcones) to congeners bearing longer linkers between the aromatic moieties. Nine 1,ω-diarylalkenones, including curcumin and bisdemethoxycurcumin, were evaluated in the chick heart invasion assay. Unfortunately, these compounds proved less potent and more toxic than earlier evaluated chemotypes. In the 1,3-diarylpenta-2,4-dien-1-one series, fluoro and/or trimethoxy substitution caused an increase in potency. This agrees with observations made earlier for the chalcone class.

Synthesis, characterization and biological activity studies of some substituted pyrimidine derivatives

A new series of substituted 1-phenyl-3-styryl-4,5-dihydo-1H-pyrazoles (TP1-TP9) has been synthesized by the cyclisation of chalcones with phenyl hydrazine and glacial acetic acid and substituted 4-styryl-pyrimidin-2-ols (LP1-LP9) have been synthesized by the condensation of chalcones with urea in the presence of 40% NaOH as a base. The intermediate substituted 1,5-diphenylpenta-2,4-dien-1-ones were synthesized by condensing cinnamaldehyde with various substituted aromatic ketones in presence of 20% NaOH. The title compounds obtained were characterized by IR, 1H NMR, mass spectral data and were screened for antimicrobial, anticancer and antitubercular activity.

One-pot synthesis of cinnamylideneacetophenones and their in vitro cytotoxicity in breast cancer cells

Design, synthesis, and bioactivities screening of a diaryl ketone-inspired pesticide molecular library as derived from natural products

Three natural products, 1,5-diphenylpentan-1-one, 1,5-diphenylpent-2-en-1-one, and 3-hydroxy-1,5-diphenylpentan-1-one, with good insecticidal activities were extracted from Stellera chamaejasme L. Based on their shared diaryl ketone moiety as 'pharmacophores', a series of diaryl ketones were synthesized and tested for insecticidal activity, acetylcholinesterase inhibitory activity, and antifungal activity. All synthesized compounds showed poor insecticidal and acetylcholinesterase inhibitory activities. Compound III with a furyl ring showed strong activities against plant pathogenic fungi. The IC50 of compound (E)-1-(2,4-dichlorophenyl)-3-(furan-2-yl)- -prop-2-en-1-one (III2) was 1.20mg/L against Rhizoctonia solani, suggesting its strong potential as a novel antifungal drug.
