A multi-gram-scale synthetic route to a novel, bifunctional normorphan 3D building block bearing orthogonally reactive vinyl MIDA boronate and N-2,4-dimethoxybenzyl (DMB) amide functional handles has been developed. Synthetic manipulation at each of the functional handles has been demonstrated including Suzuki-Miyaura cross-coupling, exo-diastereoselective hydrogenation, N-DMB group removal and lactam reduction. Normorphan cores derived from the building block satisfied AstraZeneca’s ‘rule of 2’ for building blocks and had a high fraction of sp(3) hybridised carbon atoms (Fsp(3)). A virtual lead-like library of 344 compounds derived from the building block had attractive lead-like properties. The 3D building block has been commercialised by Redbrick Molecular and is currently available for purchase. (C) 2021 Elsevier Ltd. All rights reserved.

Etoxazole is a newly registered and widely used acaricide. However, its metabolites were not fully understood and might exhibit similar or even higher toxicity than parent compound. Therefore, in this study, the metabolites of etoxazole in citrus, soil and earthworms were firstly identified by an ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS). Four potential metabolites in citrus, 11 in soil, and 8 in earthworms were determined. These metabolites were then further structural elucidated based on the fragment pathways, and accurate mass measurement. The distributions of etoxazole and its main metabolites (M1, M2, M3, M4 and M5) which were identified as the dehydrogenation, hydrolysis, oxidation products of etoxazole (M0) were also monitored in citrus, soil and earthworms at different exposure periods. The 45 days exposure experiment showed that M0 gradually decreased in citrus and soil samples by 80% and 28% of the initial amounts, respectively. In earthworm samples, M0 accumulated in the bodies of the worms during 24 days exposure and then decreased with time. The dissipation rate of etoxazole were citrus > earthworms > soil. Concentrations of M1 and M3 in soil were found continuously increased with time during the experimental period. Moreover, the persistence of M1 in earthworm samples was also observed. Great attention should be paid to these two compounds due to their potential risks to both environmental and human health. (C) 2019 Published by Elsevier Ltd.

In this study, the synthesis and characterization of novel indanone-based spiro-dihydrobenzofuran derivatives were examined. Firstly, chalcone-like compounds 4a-k, (E)-2-benzylidene-2,3-dihydro-1H-inden-1-one derivatives, were synthesized by the base-catalyzed addition of benzaldehyde derivatives to 2,3-dihydro-1 H-inden-1-one. Then Mn(OAc)(3)-mediated addition of dimedone (2) to the chalcone-like compounds gave two novel spiro-dihydrobenzofuran isomers: (3 S) -6,6-dimethyl-3-aryl-6,7-dihydro-3 H-spiro [benzofuran-2,2′-indene]-1′,4(3′ H ,5 H) -dione (5a-k) and (2′ S)-6 ,6-dimethyl-2-aryl-6 ,7-dihydro-2 H-spiro [benzofuran-3,2′-indene]-1′ ,4 (3′ H ,5 H) -dione (6a-k) in good yields. The isomers were separated by column chromatography and their structures were elucidated on the basis of spectral data (NMR, IR) and elemental analysis.

Currently, due to the HIV latency mechanism, the search continues for effective drugs to combat this issue and provide a cure for AIDS. Gnidimacrin activates latent HIV-1 replication and inhibits HIV-1 infection at picomolar concentrations. This natural diterpene was able to markedly reduce the latent HIV-1 DNA level and the frequency of latently infected cells. Therefore, gnidimacrin is an excellent lead compound, and its anti-HIV potential merits further investigation. Twenty-nine modified gnidimacrin derivatives were synthesized and evaluated in assays for HIV replication and latency activation to establish which molecular structures must be maintained and which can tolerate changes that may be needed for better pharmacological properties. The results indicated that hydroxyl substituents at C-5 and C-20 are essential, while derivatives modified at 3-OH with aromatic esters retain anti-HIV replication and latent activation activities. The half-lives of the potent GM derivatives are over 20 h, which implies that they are stable in the plasm even though they contain ester linkages. The established structure activity relationship should be useful in the development of gnidimacrin or structurally related compounds as clinical trial candidates.

The synthesis of highly acidic metal-organic frameworks (MOFs) has attracted significant research interest in recent years. We report here the design of a strongly Lewis acidic MOF, ZrOTf-BTC, through two-step transformation of MOF-808 (Zr-BTC) secondary building units (SBUs). Zr-BTC was first treated with 1 M hydrochloric acid solution to afford ZrOH-BTC by replacing each bridging formate group with a pair of hydroxide and water groups. The resultant ZrOH-BTC was further treated with trimethylsilyl triflate (Me3SiOTf) to afford ZrOTf-BTC by taking advantage of the oxophilicity of the Me3Si group. Electron paramagnetic resonance spectra of Zr-bound superoxide and fluorescence spectra of Zr-bound N-methylacridone provided a quantitative measurement of Lewis acidity of ZrOTf-BTC with an energy splitting (Delta E) of 0.99 eV between the pi(x)* and pi(y)* orbitals, which is competitive to the homogeneous benchmark Sc(OTf)(3). ZrOTf-BTC was shown to be a highly active solid Lewis acid catalyst for a broad range of important organic transformations under mild conditions, including Diels-Alder reaction, epoxide ring-opening reaction, Friedel-Crafts acylation, and alkene hydroalkoxylation reaction. The MOF catalyst outperformed Sc(OTf)(3) in terms of both catalytic activity and catalyst lifetime. Moreover, we developed a ZrOTf-BTC@SiO2 composite as an efficient solid Lewis acid catalyst for continuous flow catalysis. The Zr centers in ZrOTfBTC@SiO2 feature identical coordination environment to ZrOTf-BTC based on spectroscopic evidence. ZrOTf-BTC@SiO2 displayed exceptionally high turnover numbers (TONs) of 1700 for Diels-Alder reaction, 2700 for epoxide ring-opening reaction, and 326 for Friedel-Crafts acylation under flow conditions. We have thus created strongly Lewis acidic sites in MOFs via triflation and constructed the MOF@SiO2 composite for continuous flow catalysis of important organic transformations.

This report describes a palladium-catalyzed decarboxylative aryl allylation between unactivated benzoic acids and allylic carbonates. This transformation successfully couples a variety of carbonates and benzoic acids in good yield (up to 94%) using 1 mol% palladium. This salt free allyl-arylation proceeds without added base, copper, or silver. The only stoichiometric byproducts are carbon dioxide and tert-butanol.

Herein, we describe two novel strategies for the synthesis of esters, as achieved under high-speed ball-milling (HSBM) conditions at room temperature. In the presence of I-2 and KH2PO2, the reactions afford the desired esterification derivatives in 45% to 91% yields within 20 min of grinding. Meanwhile, using KI and P(OEt)(3), esterification products can be obtained in 24% to 85% yields after 60 min of grinding. In addition, the I-2/KH2PO2 protocol was successfully extended to the late-stage diversification of natural products showing the robustness of this useful approach. Further application of this method in the synthesis of inositol nicotinate was also discussed.
