In this report, the synthesis of amides from aldoximes (Beckmann rearrangement) has been reported using cobalt(II) porphyrin covalently linked to graphene oxide as a nano heterogeneous catalyst. The prepared catalyst was characterized by applying of FT-IR, TGA, TEM, SEM, EDX, ICP and UV-Vis techniques. All analyses confirm the successful insertion of cobalt into the porphyrin ring and covalently linkage of Co-Porphyrin on the graphene oxide. Moreover, the prepared catalyst was applied in order to investigate its performance in the Beckmann rearrangement. This heterogeneous catalyst exhibited excellent catalytic efficiency with a high yield of products. Also, the suggested catalyst could be recycled for five runs without a dramatic decrease in its catalytic activity or metal leaching.

A series of indazolyl-substituted piperidin-4-yl-aminopyrimidines (IPAPYs) were designed from two potent HIV-1 NNRTIs piperidin-4-yl-aminopyrimidine 3c and diaryl ether 4 as the lead compounds by molecular hybridization strategy. The target molecules 5a-q were synthesized and evaluated for their anti-HIV activities and cytotoxicities in MT-4 cells. 5a-q displayed moderate to excellent activities against wild-type (WT) HIV-1 with ECK values ranging from 1.5 to 0.0064 mu M. Among them, 5q was regarded as the most excellent compound against WT HIV-1 (EC50 = 6.4 nM, SI = 2500). And also, it displayed potent activities against K103 N (EC50 = 0.077 mu M), Y181C (EC50 = 0.11 mu M), E138K (EC50 = 0.057 mu M), and moderate activity against double mutants RES056 (EC50 = 8.7 mu M). Moreover, the structure-activity relationships (SARs) were summarized, and the molecular docking was performed to investigate the binding mode of IPAPYs and HIV-1 reverse transcriptase.

Human Immunodeficiency Virus (HIV) damages the immune system and leads to the life-threatening acquired immunodeficiency syndrome (AIDS). Despite the advances in the field of antiretroviral treatment, HIV remains a major public health challenge. Nucleosides represent a prominent chemotherapeutic class for treating viruses, however their cellular uptake, kinase-mediated activation and catabolism are limiting factors. Herein, we report the synthesis and in vitro evaluation of stavudine (d4T) ProTides containing polyfluorinated aryl groups against two strains; HIV-1 (IIIB) and HIV-2 (ROD). ProTide 5d containing a meta-substituted pentafluorosulfanyl (3-SF5) aryl group showed superior antiviral activity over the parent d4T and the nonfluorinated analogue 5a. ProTide 5d has low nano-molar antiviral activity; (IC50=30 nM, HIV-1) and (IC50=36 nM, HIV-2) which is over tenfold more potent than d4T. Interestingly, ProTide 5d showed a significantly high selectivity indices with SI=1753 (HIV-1) and 1461 (HIV-2) which is more than twice that of the d4T. All ProTides were screened in wild type as well as thymidine kinase deficient (TK-) cells. Enzymatic activation of ProTide 5d using carboxypeptidase Y enzyme and monitored using both P-31 and F-19 NMR is presented.

Drug resistance is a multifactorial phenomenon that limits the action of antibiotics and chemotherapeutics. Therefore, it is essential to develop new therapeutic strategies capable of inducing cytotoxic effects circumventing chemoresistance. In this regard, the employment of natural and synthetic cationic peptides and polymers has given satisfactory results both in microbiology, as antibacterial agents, but also in the oncological field, resulting in effective treatment against several tumors, including neuroblastoma (NB). To this end, two polystyrene-based copolymers (P5, P7), containing primary ammonium groups, were herein synthetized and tested on etoposide-sensitive (HTLA-230) and etoposide-resistant (HTLA-ER) NB cells. Both copolymers were water-soluble and showed a positive surface charge due to nitrogen atoms, which resulted in protonation in the whole physiological pH range. Furthermore, P5 and P7 exhibited stability in solution, excellent buffer capacity, and nanosized particles, and they were able to reduce NB cell viability in a concentration-dependent way. Interestingly, a significant increase in reactive oxygen species (ROS) production was observed in both NB cell populations treated with P5 or P7, establishing for both copolymers an unequivocal correlation between cytotoxicity and ROS generation. Therefore, P5 and P7 could be promising template macromolecules for the development of new chemotherapeutic agents able to fight NB chemoresistance.

We describe, for the first time, a highly regioselective hydrosilylation of propargylic amines. The reaction utilizes a PtCl2/XantPhos catalyst system to deliver hydrosilanes across the alkyne to afford multifunctional allylic amines in high yields. The reaction is tolerant to a wide variety of functional groups and provides high value intermediates with two distinct functional handles. The synthetic applicability of the reaction has been shown through the synthesis of diverse ambiphilic aziridines.

An atom economic procedure for the regioselective synthesis of bridged seven-membered-ring compounds from simple reactants such as ynones and indene-1,3-dione has been developed. This process was realized through the one-pot reactions of ring-expansion of indene-1,3-dione with alkynyl ketones and successive formal [4+2] cycloaddition. The Michael addition reaction is the key for the regioselectivity of the formal [4+2] cycloaddition.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

In this study, benzyl benzoate was successfully synthesized via enzymatic acylation using three immobilized enzymes as biocatalysts. Different acyl donors (benzoic acid and benzoic anhydride), operation regimes (batch, fed-batch), mixing modes (conventional mechanical stirring and ultrasound), process parameters (temperature, substrate molar ratio of acyl donor to acyl acceptor), presence or absence of solvents, enzyme amount and type were evaluated. Benzoic acid is a solid that is difficult to solubilize and, thus, was not efficient as acyl donor for the synthesis of benzyl benzoate. On the other hand, benzoic anhydride was very effective for the acylation of benzyl benzoate, and the presence of an excess of benzyl alcohol was essential to ensure the solute-solvent intermolecular attractions and good substrate solubilization, allowing the ester synthesis to be performed in the absence of organic solvents. The ultrasound was effective in increasing increase the initial reaction rate and the final conversion (88 %). However, the Lipozyme TL-IM and RM-IM supports were damaged, and the reuse was unfeasible. The batch and fed-batch approaches in conventional stirring ensured high conversions of 92 and 90 %, respectively, for batch (anhydride: alcohol 1:6) and fed-batch (1:3) using the Lipozyme TL-IM as biocatalyst. The controlled addition of the anhydride (fed-batch) allowed the reduction of alcohol molar ratio but decreased the reaction rates, and the maximum conversions were reached only after 24 h, while the batch approach had 92 % of conversion after 6 h. The yield of benzyl benzoate was high at 6 wt.% of enzyme, low temperature (50 degrees C), and simple reactor operation (batch). Results show the feasibility of the synthesis of benzyl benzoate via acylation using a green process that may be an alternative route to the chemical synthesis.

The selective FeCl3-catalyzed oxidative cross-coupling reaction between phenols and primary, secondary, and tertiary 2-aminonaphthalene derivatives was investigated. The generality of this scalable method provides a sustainable alternative for preparing N,O-biaryl compounds that are widely used as ligands and catalysts. Based on a comprehensive kinetic investigation, a catalytic cycle involving a ternary complex that binds to both the coupling partners and the oxidant during the key oxidative coupling step is postulated. Furthermore, the studies showed that the reaction is regulated by off-cycle acid-base and ligand exchange processes.

Para C-H borylations (CHB) of tetraalkylammonium sulfates and sulfamates have been achieved using bipyridine-ligated Ir boryl catalysts. Selectivities can be modulated by both the length of the alkyl groups in the tetraalkylammonium cations and the substituents on the bipyridine ligands. Ion pairing, where the alkyl groups of the cation shield the meta C-H bonds in the counter-anions, is proposed to account for para selectivity. The 4,4′-dimethoxy-2,2′-bipyridine ligand gave superior selectivities.
