Recently, the UV/free chlorine process has gained attention as a promising technology for destroying refractory organic contaminants in the aqueous phase. We have developed a kinetic model based on first-principles to describe the kinetics and mechanisms of the oxidation of organic contaminants in the UV/free chlorine process. Substituted benzoic acid compounds (SBACs) were chosen as the target parent contaminants. We determined the second-order rate constants between SBACs and reactive chlorine species (RCS; including Cl center dot, Cl-2(-)center dot and ClO center dot) by fitting our model to the experimental results. We then predicted the concentration profiles of SBACs under various operational conditions. We analyzed the kinetic data and predicted concentration profiles of reactive radicals (HO center dot and RCS), we found that ClO center dot was the dominant radicals for SBACs destruction. In addition, we established quantitative structure activity relationships (QSARs) that can help predict the second-order rate constants for SBACs destruction by each type of reactive radicals using SBACs Hammett constants. Our first-principles-based kinetic model has been verified using experimental data. Our model can facilitate a design for the most cost-effective application of the UV/free chlorine process. For example, our model can determine the optimum chlorine dosage and UV light intensity that result in the lowest energy consumption.

Decarbonylative Sonogashira cross-coupling of carboxylic acids by palladium catalysis is presented. The carboxylic acid is activated in situ by the formation of a mixed anhydride and further decarbonylates using the Pd(OAc)(2)/Xantphos system to provide an aryl-Pd intermediate, which is intercepted by alkynes to access the traditional Pd(0)/(II) cycle using carboxylic acids as ubiquitous and orthogonal electrophilic cross-coupling partners. The methodology efficiently constructs new C(sp(2))-C(sp) bonds and can be applied to the derivatization of pharmaceuticals. Mechanistic studies give support to decarbonylation preceding transmetalation in this process.

An efficient method for the directing group controlled rhodium-catalyzed addition reaction of oxa/azabicylic alkenes with aromatic ketones and benzoic acids has been developed. The ketones and benzoic acids afforded different addition products when reacted with oxa/azabicyclic alkenes. The reaction between ketones and azabenzonorbornadienes furnished the ring-opening addition products. The reaction between benzoic acids and aza/oxabicyclic alkenes proceeded in the absence of silver salt, giving the 1:2 hydroarylation products in yields up to 96%.

Synthetic studies on palmarumycin C-6 with a naphthyl acetal at the C-3 position in 4,7-dihydroxy-1-indanone as a lower homologue of spirobisnaphthalenes are described herein. We investigated three approaches: 1) Nazarov cyclization of benzoylketene acetal, 2) intramolecular Friedel-Crafts acylation of naphtho[1,8-de]-1,3-dioxin-2-aryl-2-acetic acid chloride, and 3) double oxa-Michael addition of 1,8-dihydroxynaphthalene to 3-bromo-l-indenone. The last approach successfully afforded the natural product after the removal of acetates that serve as protecting groups for phenolic hydroxyls under acidic conditions.

Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

A simple, facile and efficient method has been developed for the Friedel-Crafts benzoylation of arenes using magnetic gamma-Fe2O3 nanoparticles under solvent-free sonication. The gamma-Fe2O3 nanoparticles were used as an efficient and magnetically recoverable catalyst for the synthesis of aromatic ketones in good to excellent yields at room temperature under solvent-free. The reaction occurred with high regioselectivity under mild condition. The magnetic gamma-Fe2O3 nanoparticles are economically synthesized in large-scale, easily separated from the reaction mixture by an external magnet and able to be reused several times without significant loss of the catalytic performance, which make them easy application to industrial processes.

Friedel-Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.

Polyfunctional arenes are an important part of the chemical value chain. To improve the efficiency of their synthesis, we have investigated a multicomponent approach built upon the Catellani platform. Here, we describe a 4-component coupling of aryl iodides lacking an ortho substituent that installs 3 discrete functional groups on the arene in a single step. The process is regio- and chemoselective and uncovers remote substituent effects that have a pronounced influence over inter mediate Pd-(II) complexes. These intermediates have been a long-standing focus of the Catellani-reaction development, but persistent challenges have given rise to the well-known ortho effect. We now show that the ortho effect can be a positive element of reaction design, and that previously problematic iodides can now be used in complexity-generating transformations. In expanding the scope of the Catellani platform, we hope to provide mechanistic considerations to guide future reaction design, while also improving the environmental footprint of synthesizing polyfunctional arenes.

We report the practical synthesis of a key fragment of islatravir (MK-8591), a novel nucleoside reverse transcriptase translocation inhibitor (NRTTI) currently under investigation for treatment and pre-exposure prophylaxis (PrEP) against HIV infection. The fragment, the unnatural nucleobase 2-fluoroadenine, is incorporated into MK-8591 via a biocatalytic aldolglycosylation cascade, which imposes stringent requirements for its synthesis and isolation. Presented herein is the development work leading to a practical, scalable route from guanine, featuring a dual fluorination approach to a novel 9-THP-2,6-difluoropurine intermediate that enables a mild, highly selective, direct amination. This one-pot fluorination/amination sequence utilizes a direct isolation to deliver high purity 9-THP-2-fluoroadenine, which features ideal properties with respect to reactivity, solubility, and crystallinity. An acid-catalyzed liberation of 2-fluoroadenine in aqueous buffer delivers the appropriate purity profile to facilitate the enzymatic cascade to access MK-8591.
