An efficient Cu(II)-catalyzed radical addition of maleimides has been achieved. The identified copper catalyst enables the formation of oxime radicals (N-O-center dot) by cleaving the O-H bond in ketoximes, followed by the radical addition to N-substituted maleimides. The oxime radicals (N-O-center dot) were detected and confirmed by EPR spectroscopy and variable-temperature H-1 NMR. The simple one-pot reaction realizes the facile preparation of a variety of oxime ether adduct products in moderate to good yields. (C) 2019 Elsevier Ltd. All rights reserved.

Transition-metal-catalyzed cross-electrophile C(sp(2))-(sp(3)) coupling and C-H alkylation reactions represent two efficient methods for the incorporation of an alkyl group into aromatic rings. Herein, we report a Pd-catalyzed cascade cross-electrophile coupling and C-H alkylation reaction of 2-iodo-alkoxylarenes with alkyl chlorides. Methoxy and benzyloxy groups, which are ubiquitous functional groups and common protecting groups, were utilized as crucial mediators via primary or secondary C(sp(3))-H activation. The reaction provides an innovative and convenient access for the synthesis of alkylated phenol derivatives, which are widely found in bioactive compounds and organic functional materials.

ortho-Selective carbene C-H insertion of unprotected phenols is achieved with dimethyl diazomalonate under the catalysis of [Rh(COD)Cl](2). After the C-H insertion, subsequent cyclization and electrophilic addition of another carbene molecule affords tris-carboxylate-substituted 2-benzofuranones as the final reaction products. The enantioselective variant has been developed with the use of chiral diene ligands. Mechanistic experiments indicate that a transient oxonium ylide directing group might be responsible for the regiocontrol at the C-H activation step.

Acid-mediated one-pot domino reactions of substituted 2-amino thiazoles, substituted benzaldehydes and cyclic diketones have been developed for the synthesis of novel and architecturally unique thiazolo[2,3-b]quinazolinone derivatives under microwave irradiation. In this protocol, a series of thiazolo[2,3-b]quinazolinone derivatives have been synthesized and the excellent fluorescence behaviors of some of the molecules have been reported based on the incorporation of different electron-donating and electron-withdrawing substituents on the aryl moieties of the target molecules.

An efficient and sustainable protocol for the hydration of alkynes has been developed under metal/acid/catalyst/ ligand-free conditions in a water/ethyl lactate mixture. The hydrogen-bond network in the ethyl lactate and water mixture plays a crucial and decisive role in activating the alkynes for hydration to afford the corresponding methyl ketones. This strategy gives the Markovnikov (ketone) addition product selectively over other possible products. The essential role of hydrogen bonding has been confirmed by experimental and theoretical techniques. A probable mechanism has been suggested by various control tests. The efficacy of the method has been further explored for the competent production of value-added alpha,beta-unsaturated carbonyl compounds through the reaction of aldehydes with alkynes as ketonic surrogates. The environmentally benign hydration method takes place under mild conditions, has broad functional-group compatibility, and uses the ethyl lactate/water (1:3) medium as a green alternative in the absence of any hazardous, harmful, or expensive substances.

A wide range of commercially available aldehydes have been applied to Knoevenagel condensation reaction to give E-alkenylphosphine oxides and vinylphosphine oxides. The readily available phosphinoylacetic acids derived from P(O)-H compounds were used as the starting materials in the reaction, providing a highly stereoselective and efficient method for constructing alpha,beta-unsaturated phosphine oxides. Moreover, this simple and practical procedure provides an alternative and more environmentally friendly synthesis strategy for this type of P-functionalized alkenyl compounds.

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.

Chemical ionization of organic compounds with negligible vapor pressures (VP) is achieved at atmospheric pressure when the proximal sample is exposed to corona discharge. The vapor-phase analyte is produced through a reactive olfaction process, which is determined to include electrostatic charge induction in the proximal condensed-phase sample, resulting in the liberation of free particles. With no requirement for physical contact, a new contained nano-atmospheric pressure chemical ionization (nAPCI) source was developed that allowed direct mass spectrometry analysis of complex mixtures at a sample consumption rate less than nmol/min. The contained nAPCI source was applied to analyze a wide range of samples including the detection of 1 ng/mL cocaine in serum and 200 pg/mL caffeine in raw urine, as well as the differentiation of chemical composition of perfumes and beverages. Polar (e.g., carminic acid; estimated VP 5.1 x 10(-25) kPa) and nonpolar (e.g., vitamin D2; VP 8.5 x 10(-11) kPa) compounds were successfully ionized by the contained nAPCI ion source under ambient conditions, with the corresponding ion types of 78 other organic compounds characterized.

Phenolic, lignin-derived substrates have emerged as desirable biorenewable chemical feedstocks for coupling reactions. A radical-mediated conversion of phenol derivatives to anilines is reported, using unfunctionalized hydroxamic acids as the N-centered radical source. The applicability of this triethyl phosphite mediated O-atom transfer approach, which tolerates a range of steric and electronic demands to naturally occurring phenols and lignin models, has been demonstrated in this work to access the corresponding aniline derivatives.

The multicomponent synthesis of 1-amidoalkyl naphthols and polyhydroquinolines has been developed as an atom-economic procedure catalyzed by a deep eutectic solvent ([CholineCl][ZnCl2](3)). The reactions proceed smoothly at low temperatures for a short reaction time without the use of toxic and volatile organic solvents. Deep eutectic solvents are capable of not only allowing multicomponent reactions to proceed in high yield but also controlling the selectivity towards desired products. The mechanistic insight was examined by HRMS (ESI) to propose a plausible mechanism. Furthermore, [CholineCl][ZnCl2](3) can be recycled in up to three consecutive cycles with an insignificant loss of catalytic activity under the optimized conditions.
