N-Acylpyrrole-type amides are a class of versatile building blocks in asymmetric synthesis. We report that by employing Ni(COD)(2)/2,2 ‘-bipyridine (5 mol%) catalytic system, the direct, catalytic alcoholysis of N-acylpyrrole-type aromatic and aliphatic amides with both primary and secondary alcohols can be achieved efficiently under very mild conditions (rt, 1 h) even at gram scale. By increasing the catalyst loading to 10 mol%, prolonging reaction time (18 h), and/or elevating reaction temperature to 50 degrees C/80 degrees C, the reaction could be extended to both complex and hindered N-acylpyrroles as well as to N-acylpyrazoles, Nacylindoles, and to other (functionalized) primary and secondary alcohols. In all cases, only 1.5 equiv. of alcohol were used. The value of the method has been demonstrated by the racemization-free, catalytic alcoholysis of chiral amides yielded from other asymmetric methodologies.

A simple and general approach towards the total syntheses of several iridolactones such as (+/-)-boschnialactone, (+/-)-7-epi-boschnialactone, (+/-)-teucriumlactone, (+/-)-iridomyrmecin, (+/-)-isoboonein, (+/-)-7-epi-argyol, (+/-)-scabrol A, (+/-)-7-epi-scabrol A, and (+/-)-patriscabrol as well as the putative structure of scholarein A is delineated. The synthetic strategy features a diastereoselective intramolecular Pauson-Khand reaction (IPKR) to construct the iridoid framework followed by some strategic synthetic manipulations to access the targeted monoterpenes including those having diverse oxy-functionalization patterns and with 3-5 contiguous stereogenic centres in a highly stereocontrolled manner. Also, the present endeavour includes the first total synthesis of scabrol A.

New chiral regioisomeric gamma-hydroxyphosphine ligands were synthesized from alpha-pinene. The key transformation was the thermal [2,3]-sigmatropic rearrangement of allyldiphenylphosphinites, obtained from (1R,2R,4S,5R)-3-methyleneneoisoverbanol and (1R,2R,3R,5R)-4-methyleneneoisopinocampheol, to allylphosphine oxides. Hydroxy groups were introduced stereoselectively through a hydroboration-oxidation reaction proceeding from the less hindered site providing a trans relationship between the hydroxy and the phosphine substituents.

The Passerini three-component reaction between acenaphthylene-1,2-dione, alkyl isocyanides, and carboxylic acids, leading to the formation of alpha-acyloxyamides in common organic solvents (CH2Cl2, MeOH) and choline chloride-based deep eutectic solvent, is described. The reaction in the latter solvent proceeded faster compared to common organic solvents. The structure of a typical product was confirmed by X-ray crystallography. [GRAPHICS] .

Preparation of an ordered mesoporous polypyrrole/carbon (PPy/OMC) composite has been described through a two-step nanocasting process using KIT-6 as a template. Characterization of the PPy/OMC nanocomposite by various analysis methods such as TEM, XRD, TGA, SEM and N-2 sorption confirmed the preparation of a material with ordered mesoporous structure, uniform pore size distribution, high surface area and high stability. This nanocomposite was then used for the immobilization of palladium nanoparticles. The nanoparticles were almost uniformly distributed on the support with a narrow particle size of 20-25 nm, confirmed by various analysis methods. Performance of the Pd@PPy/OMC catalyst was evaluated in the aerobic oxidation of various primary and secondary alcohols on water as a green solvent, giving the corresponding carboxylic acids and ketones in high yields and excellent selectivity. The catalyst could also be reused for at least 10 reaction runs without losing its catalytic activity and selectivity. High catalytic efficiency of the catalyst can be attributed to a strong synergism between the PPy/OMC and that of supported Pd nanoparticles.

The present study reports the convenient synthesis, spectroscopic characterization, bio-assays and computational evaluation of a novel series of N-acyl-1H-imidazole-1-carbothioamides. The screened derivatives displayed excellent antioxidant activity, moderate antibacterial and antifungal potential. The screened derivatives were found to be highly biocompatible against hRBCs. Molecular docking ascertained the mechanism and mode of action towards the molecular target delineating that ligands and complexes were stabilized at the active site by electrostatic and hydrophobic forces in accordance to the corresponding experimental results. Docking simulation provided additional information about the possibilities of inhibitory potential of the compounds against RNA. Computational evaluation predicted that N-acyl-1H-imidazole-1-carbothioamides 5c and 5g can serve as potential surrogates for hit to lead generation and design of novel antioxidant and antibacterial agents.

The insect beta-N-acetylhexosaminidase OfHex1 from Ostrinia furnacalis (one of the most destructive agricultural pests) has been considered as a promising pesticide target. In this study, a series of novel and readily available ureido thioglycosides were designed and synthesized based on the catalytic mechanism and the co-crystal structures of OfHex1 with substrates. After evaluation via enzyme inhibition experiments, thioglycosides 11c and 15k were found to have inhibitory activities against OfHex1 with the K-i values of 25.6 mu M and 53.8 mu M, respectively. In addition, all these ureido thioglycosides exhibited high selectivity toward OfHex1 over hOGA and HsHexB (K-i > 100 mu M). Furthermore, to investigate the inhibitory mechanism, the possible binding modes of 11c and 15k with OfHex1 were deduced based on molecular docking analysis. This work may provide useful structural starting points for further rational design of potent inhibitors of OfHex1.

An expeditious method for the synthesis of homo and heterochiral dipeptides containing L-alanine and D/L 2-methyl allo-hydroxyl prolines was developed using direct aminolysis of bicyclic lactones derived from D/L alanine. The impact of C-2 methylation and its spatial orientation on the pyrrolidine ring puckering and prolyl amide bond configuration was ascertained by solution NMR studies. The present studies reveal that C-2 methylation causes the prolyl amide bond to exist exclusively in the trans geometry in both homo-and heterochiral dipeptides. However, the spatial orientation of the C-2 methyl group and its i + 2 position in appropriately capped model dipeptides may nucleate into a turn like structure.

An efficient one-pot and regioselective synthesis of 3,4-dihydroquinazolines and 4,5-dihydro-3H-1,4-benzodiazepin-3-ones by Ugi/Staudinger/aza-Wittig sequence has been developed. The Ugi reactions of 2-azidobenzylamines, aldehydes, acids (or alpha-keto acids) and isocyanides produced the azide intermediates, which were then treated with tributylphosphine or triphenylphosphine to give poly-substituted 3,4-dihydroquinazolines or 4,5-dihydro-3H-1,4-benzodiazepin-3-ones in moderate to good yields by tandem Standinger/aza-Wittig reactions.

Although there is much interest in the use of azobenzenes (ABs) as molecular switches for biological and material science applications, there is still need for systematic rationalization of their photophysical properties determined at both experimental and theoretical level. We present here the (re-) evaluation of the properties of some AB derivatives in the context of their geometrical substitution (para or meta) and nature of substituent effects (i.e. electron-donating groups, EDGs or electron-withdrawing groups, EWGs). Results of comprehensive experimental studies of their photophysical properties, thermal stabilities and functioning in reducing environments are rationalized by DFT calculations. As the associated n-pi* bands of the trans (E) and cis (Z) isomers of the studied ABs overlap, it is difficult to obtain high cis-to-trans conversion, however we have proved that by manipulation of the substituents position, the content of the cis isomer at the photostationary state (PSS) could be enhanced up to 30%. Moreover, we show that the presence of -NHCO- group at para positions contributes to reducing the effective bond order of the azo group resulting in the reduction of the height of the energy barrier for conversion and reduces the half-life of the cis isomer. Finally, electron deficient ABs are found to be more stable under reducing environments.
