Silyl-substituted ketenes are attractive molecular building blocks due to their stability and ease of storage, as opposed to unstable alkyl and aryl ketenes. To better understand the reactivity of silyl ketenes and, in turn, their use in the preparation of highly functionalized small molecules, the reaction of silyl ketenes with different nucleophiles was studied. The addition of alcohol, amine, or thiol nucleophiles to the central carbon of silyl ketene, followed by proton transfer afforded alpha-silyl ester, amide, or thio-ester, respectively. Catalytic amounts of Lewis acid greatly increase the rate of the reaction, and the impact of nucleophile, Lewis acid, and silyl substituent are evaluated. The small molecules produced from these reactions give insight into the use of silyl ketenes as building blocks for complex molecular structures.

Multidrug resistance (MDR) is a major obstacle for effective chemotherapeutic treatment of cancer frequently leading to failure of the therapy. MDR is often associated with the overexpression of ABC transport proteins like ABCB1 or ABCG2 which efflux harmful substances out of cells at the cost of ATP hydrolysis. One way to overcome MDR is to apply potent inhibitors of ABC transporters to restore the sensitivity of the cells toward cytostatic agents. This study focusses on the synthesis and evaluation of novel 2,4-disubstituted quinazoline derivatives regarding the structure-activity-relationship (SAR), their ability to reverse MDR and their mode of interaction with ABCG2. Hence, the inhibitory potency and selectivity toward ABCG2 was determined. Moreover, the intrinsic cytotoxicity and the reversal of MDR were investigated. Interaction type studies with the substrate Hoechst 33342 and conformational analyses of ABCG2 with 5D3 monoclonal antibody were performed for a better understanding of the underlying mechanisms. In our study we could further enhance the inhibitory effect against ABCG2 (compound 31, IC50: 55 nM) and identify the structural features that are crucial for inhibitory potency, the impact on transport activity and binding to the protein.

A cobalt-complex-catalyzed borylation of a wide range of alkyl halides with a diboron reagent (B(2)pin(2) or B(2 )neop(2)) has been developed under mild reaction conditions, demonstrating the first cobalt-mediated cross-coupling with alkyl electrophiles. This protocol allows alkyl boronic esters to be accessed from alkyl halides, including alkyl chlorides, which were used rarely as coupling partners. Mechanistic studies reveal the possible involvement of an alkyl radical intermediate in this cobalt-mediated catalytic cycle.

The persistent reservoir of cells latently infected with human immunodeficiency virus (HIV)-integrated proviral DNA necessitates lifelong suppressive antiretroviral therapy (ART). Epigenetic targeted compounds have shown promise as potential latency-reversing agents; however, these drugs have undesirable toxicity and lack specificity for HIV. We utilized a novel HEK293-derived FlpIn dual-reporter cell line, which quantifies specific HIV provirus reactivation (LTR promoter) relative to nonspecific host cell gene expression (CMV promoter), to identify the 5-substituted 2-acylaminothiazole hit class. Here, we describe the optimization of the hit class, defining the functionality necessary for HIV gene activation and for improving in vitro metabolism and solubility. The optimized compounds displayed enhanced HIV gene expression in HEK293 and Jurkat 10.6 latency cellular models and increased unspliced HIV RNA in resting CD4+ T cells isolated from HIV-infected individuals on ART, demonstrating the potential of the 2-acylaminothiazole class as latency-reversing agents.

In this work, we report a thorough investigation of the reaction of phenols with aryldiazoacetates. Mechanistic studies using different spectroscopic methods and theoretical calculations suggest a hydrogen bond between phenol and aryldiazoacetates, which can be modulated by the phenol acidity. The pK(A) of phenol and therefore the hydrogen bond plays an important role in a subsequent photoinduced proton transfer reaction to give the formal O-H functionalization product of phenols.

A series of azamacrolides containing the carbamate or urea moiety were synthesized and evaluated for their fungicidal activities against several agriculturally important pathogens. In addition, they were investigated for their ability to inhibit quorum sensing in Agrobacterium tumefaciens. The results showed that most of the derivatives had moderate to high fungicidal activities against the tested fungi, especially towards Sclerotinia sclerotiorum. Additionally, D16-19 could be used as a potential broad-spectrum fungicide while D16-4 exhibited a fungicidal activity (EC50 = 1.87 mg L-1) similar to that of carbendazim (EC50 = 1.34 mg L-1) against S. sclerotiorum. The three-dimensional Quantitative Structure-Activity Relationship (3D-QSAR) models were also established based on the experimental results and they would provide valuable information for further optimization. Moreover, D16-17 not only showed a better fungicidal activity against S. sclerotiorum but also had the highest ability to inhibit quorum sensing. These findings suggested that some azamacrolide compounds hold potential for the development of novel fungicides or inhibitors of quorum sensing.

Substances containing a spirooxindole framework display important biological activities. Natural alkaloid capparine A [(S)-(-)-1] has an anti-inflammatory effect. In the present study, attention has been paid to the first total synthesis of natural capparine A [(S)-(-)-1]. Racemic capparine A [(-+/-)-1] was synthesized by bromospirocyclization of 6-methoxy-1-Boc-brassinin with water, followed by oxidation of obtained spirobrassinol derivatives and removal of the Boc group. Synthesized racemic capparine A [(-+/-)-1] was enantioresolved by derivatization with (1R,2S,5R)-menthyl chloroformate, chromatographic separation of diastereoisomers and the cleavage of the chiral auxiliary using sodium methoxide. Screening of antiproliferative activity against human cancer cells revealed no anti-proliferative activity of the capparine A [(S)-(-)-1]. (C) 2020 Elsevier Ltd. All rights reserved.

Dialkylation of Indoles with Trichloroacetimidates to Access 3,3-Disubstituted Indolenines

2-Substituted indoles may be directly transformed to 3,3-dialkyl indolenines with trichloroacetimidate electrophiles and the Lewis acid TMSOTf. These reactions provide rapid access to complex indolenines which are present in a variety of complex natural products and medicinally relevant small molecule structures. This method provides an alternative to the use of transition metal catalysis. The indolenines are readily transformed into spiroindoline systems which are privileged scaffolds in medicinal chemistry.
