A transition-metal-free method for the alkylation of gem-diborylalkanes with alpha,beta-unsaturated ketones has been developed. It is demonstrated that the alpha-boryl radicals can be generated efficiently from gem-diborylalkanes with the aid of catechol and oxidants. The alpha-boryl radicals formed through such process can be engaged in conjugate addition reaction with alpha,beta-unsaturated ketones. This transformation is a straightforward method for the synthesis of gamma-borylketones.

A straightforward and general method has been developed for the synthesis of chalcone derivatives by a Claisen-Schmidt reaction in the presence of PPh3/I-2 in 1,4-dioxane under reflux temperatures. With the condensation of the aromatic ketone and aldehyde occurring at non-strongly alkaline conditions, our proposed method significantly expands the range of applicable substrates, especially for groups that are unstable under alkaline conditions.

Aziridines are useful synthetic building blocks, widely employed for the preparation of various nitrogen-containing derivatives. As the current methods require the use of prefunctionalized amines, the development of a synthetic strategy toward aziridines that can establish the union of alkenes and amines would be of great synthetic value. Herein, we report an electrochemical approach, which realizes this concept via an oxidative coupling between alkenes and primary alkylamines. The reaction is carried out in an electrochemical flow reactor leading to short reaction/residence times (5 min), high yields, and broad scope. At the cathode, hydrogen is generated, which can be used in a second reactor to reduce the aziridine, yielding the corresponding hydroaminated product. Mechanistic investigations and DFT calculations revealed that the alkene is first anodically oxidized and subsequently reacted with the amine coupling partner.

A cheap, facile and metal-free photochemical protocol for the activation of aromatic aldehydes has been developed. Utilizing thioxanthen-9-one as the photocatalyst and cheap household lamps as the light source, a variety of aromatic aldehydes have been activated and subsequently converted in a one-pot reaction into amides, hydroxamic acids and esters in good to high yields. The applicability of this method was highlighted in the synthesis of Moclobemide, a drug against depression and social anxiety. Extended and detailed mechanistic studies have been conducted, in order to determine a plausible mechanism for the reaction.

(E)-4-Amino-N’-(substituted benzylidene) benzohydrazides (1-8) were synthesized by condensing 4-aminobenzohydrazide with an appropriate aldehyde in the molar ratio of 1:1 in methanol as solvent. Single crystal X-ray diffraction has been recorded for compound 1. For all the synthesized compounds, FT-IR, H-1 and C-13 NMR spectra have been recorded. Also antibacterial and docking studies have been done for all compounds 1-8. Since for compound 1 only single crystal X-ray analysis has been carried out, its structural characterization have been done in detail, characterisation of remaining compounds 2-8 have been carried out by comparing their FT-IR, H-1 and C-13 NMR spectral data with that of compound 1. Single crystal X-ray analysis of 1 show that the compound exists in E-configuration about azomethine double bond. The crystal state of the compound was stabilised by the hydrogen bond present in the molecule. DFT calculations using the B3LYP/6-311++G method have been carried out for 1 to get the optimized geometry, IR and NMR frequencies, Mulliken charge distribution, molecular electrostatic potential (MEP) and energies of HOMO – LUMO. A good agreement between the DFT predicted and the experimentally measured IR and NMR spectra of 1 was found. Analysis of MEP and Mulliken atomic charges bar diagram of 1, confirms the chemical reactivity and existence of intermolecular hydrogen bonding of the molecule. The result of antibacterial and antifungal activities shows that the compounds 2, 4, 7 and 8 showed good antibacterial activity against the tested bacteria and the compounds 1, 3, 5 and 6 showed good antifungal activities against all the three fungal strains. These results showed that electron donating and electron withdrawing groups play important roles in antibacterial and antifungal activities of the compounds1-8, respectively. Molecular docking studies of compounds 1-8 shows that the various ligand of compounds 1-8 shows glide score values lies between -5.923 to -7.298, among these the compounds 6 and 8 showed excellent glide score values.

We report a new method for constructing propionate-derived trisubstituted alkene motifs in a stereoselective manner. 1-Substituted 1,1-di(pinacolatoboryl)-(E)-alk-2-enes are generated in situ from 1-substituted 1,1-di(pinacolatoboryl)alk-3-enes through ruthenium(II)-catalyzed double-bond transposition. These species undergo a chiral phosphoric acid catalyzed allylation reaction of aldehydes to produce the E isomers of anti-homoallylic alcohols. On the other hand, the corresponding Z isomers of anti-homoallylic alcohols are obtained when a dimeric palladium(I) complex is employed as the catalyst for this double-bond transposition. Thus, both E and Z isomers can be synthesized from the same starting materials. A B-C(sp(2)) bond remaining with the allylation product undergoes the Suzuki-Miyaura cross-coupling reaction to furnish a propionate-derived trisubstituted alkene motif in a stereo-defined form. The present method to construct the motifs with (E)- and (Z)-alkenes are successfully applied to the syntheses of (+)-isotrichostatic acid, (-)-isotrichostatin RK, and (+)-trichostatic acid, respectively.

A new approach to functionalize porphyrinoids was developed based on the Vilsmeier formylation followed by the azine formation and a new class of the compounds namely azines of porphyrinoids was obtained. Variously substituted azine porphyrins, chlorins and their dyads were synthesized, and their structural and electronic parameters were studied with X-ray diffraction analysis, electronic absorption and emission spectra, electrochemistry and DFT calculations. Azine represents a very peculiar bridge with an unclear conjugation ability affecting optical properties of chromophores. This work was aimed to reveal azine properties and the influence of the azine bridge on the chromophores linked. The results of investigation allowed to conclude that azine bridge can partly be regarded as a conjugation switch with a high threshold level of switching, where limited conjugation in the ground state can be greatly increased at higher energy states of the azine molecule.

There is a continuous need in drug development approach for synthetic anticancer analogues with new therapeutic targets to diminish chemotherapeutic resistance of cancer cells. This study presents new group of synthetic thienopyrimidine analogues (1-9) aims as mGluR-1 inhibitors with anticancer activity. In-vitro antiproliferative assessment was carried out using viability assay against cancer cell lines (MCF-7, A-549 and PC-3) compared to WI-38 normal cell line. Analogues showed variable anticancer activity with IC50 ranging from 6.60 to 121 mu g/mL with compound 7b is the most potent analogue against the three cancer cell lines (MCF-7; 6.57 +/- 0.200, A-549; 6.31 +/- 0.400, PC-3;7.39 +/- 0.500 mu g/mL) compared to Doxorubicin, 5-Flurouracil and Riluzole controls. Selected compounds were tested as mGluR-1 inhibitors in MCF-7 cell line and results revealed compound 7b induced significant reduction in extracellular glutamate release (IC50; 4.96 +/- 0.700 mu M) compared to other analogues and next to Riluzole (IC50; 2.80 +/- 0.500 mu M) of the same suggested mode of action. Furthermore, both cell cycle and apoptosis assays confirmed the potency of compound 7b for early apoptosis of MCF-7 at G2/M phase and apoptotic positive cell shift to (91.4%) compared to untreated control (19.6%) and Raptinal positive control (51.4%). On gene expression level, compound 7b induced over-expression of extrinsic (FasL, TNF-alpha and Casp-8), intrinsic (Cyt-C, Casp-3, Bax) apoptotic genes with down-regulation of anti-apoptotic Bcl-2 gene with boosted Bax/Bcl-2 ratio to 2.6-fold increase. Molecular docking and dynamic studies confirmed the biological potency through strong binding and stability modes of 7b where it was faster in reaching the equilibrium point and achieving the stability than Riluzole over 20 ns MD. These results suggest compound 7b as a promising mGluR inhibitory scaffold with anticancer activity that deserves further optimization and in-depth In-vivo and clinical investigations.
