Utilizing a chiral bicyclic imidazole organocatalyst and adopting a continuous injection process, an alternative route has been developed for the efficient synthesis of chiral phthalidyl ester prodrugs via dynamic kinetic resolution of 3-hydroxyphthalides through enantioselective acylation (up to 99 % ee). The computational studies suggest a general base catalytic mechanism differing from the widely accepted nucleophilic catalytic mechanism. The structure analysis of the key transition states shows that the CH-pi interactions and not the previously considered cation/pi-pi interactions between the catalyst and substrate is the dominant factor giving rise to the observed stereocontrol.

To improve the efficiency of the photocatalytic decarbonylation of cyclopropenones, the effects of substituents on cyclopropenone were explored. A benzothiophene-substituted aminocyclopropenone exhibited significantly improved decarbonylation efficiency to produce the corresponding ynamine, which worked as a potent dehydration condensation agent. The benzothiophene derivative was applicable to the photocatalytic reaction in the presence of potential excited-state quenchers such as oxygen and anilines. The high catalyst sensitivity would be attributed to the involvement of triplet energy transfer reaction pathway, which was not observed in the reaction with previously reported aminocyclopropenones.

A diverse range of ureas, N-acylureas, carbamates, and thiocarbamates has been synthesized in good to excellent yields by reacting N-acylbenzotriazoles individually with amines or amides or phenols or thiols in the presence of diphenylphosphoryl azide (DPPA) as a suitable azide donor in anhydrous toluene at 110 degrees C for 3-4 hours. In this route, DPPA was found to be a good alternative to trimethylsilyl azide and sodium azide for the azide donor in Curtius degradation. The high reaction yields, one-pot and metal-free conditions, straightforward nature, easy handling, use of readily available reagents, and in many cases avoidance of column chromatography are the notable features of the devised protocol.

Metal homoenolates are valuable synthetic intermediates which provide access to beta-functionalized ketones. In this report, we disclose a Ni-catalyzed beta-alkylation reaction of cyclopropanol-derived homoenolates using redox-active N-hydroxyphthalimide (NHPI) esters as the alkylating reagents. The reaction is compatible with 1 degrees, 2 degrees, and 3 degrees NHPI esters. Mechanistic studies imply radical activation of the NHPI ester and 2e beta-carbon elimination occurring on the cyclopropanol.

O-Acylation of 1,3-dicarbonyl compounds provides enol esters which act as precursors for the synthesis of chiral alcohols, natural products, heterocycles and functional materials. Perfluoroalkanosulfonyl fluoride (RfSO(2)F) is a class of excellent hydroxyl-activating reagent, and has been extensively developed and used in the formation of C-F, C-O, C-N and C-S bonds in organic synthesis. In this work one-step O-acylation of 1,3-dicarbonyl compounds (1,3-diketones and beta-ketonic esters) with carboxylic acids activated by RfSO2F in alkaline media was disclosed, and the corresponding O-acylation products (enol esters) were generated in moderate to good yields. The optimized reaction conditions are as follows: 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as base, CH2Cl2 as solvent, n-C4F9SO2F as activating reagent, room temperature for 30 min and the molar ratio of n(1,3-dicarbonyls): n(RCOOH): n(RfSO2F): n(DBU) being 1.0 : 1.0 : 1.0 : 4.0. A novel reagent for one-step O-acylation of 1,3-dicarbonyl compounds with carboxylic acids was developed. The application of RfSO2F in organic synthesis was further expanded.

Through topology-guided synthesis, a Zr-based mesoporous MOF was successfully constructed, adopting a b-cristobalite-type structure. The MOF is embedded with well-arranged terpyridine coordination sites for facile post-syntheticmetalation, and can be effectively used as a general scaffold for the preparation of noble-metal-free catalysts. For instance, the scaffolded metal@MOF material exhibits highly efficient catalytic activity for alkene epoxidation and arene borylation.

An efficient and BF3 center dot Et2O-catalyzed chemoselective synthesis of diversified 1,3-diarylisobenzofuran in a high yield has been described. The reaction proceeds through sequential hydroarylation-cyclization between 2-formylarylketones and electron-rich arenes/heteroarenes. Advantageous features of the developed methodology include operational simplicity, a broad substrate scope, and applicability towards gram scale synthesis. The utility of isobenzofuran derivatives as the diene was extended to the synthesis of [4+2] cyclo-adducts with DMAD and the synthesis of 1,2-dicarbonylarenes in good yields.

The reaction of TMS-ethers of 2,4-diaryl-1,1,1-trifluorobut-3-en-2-ols with arenes in TfOH at room temperature for 5 min results in the formation of trans-/cis-1,3-diaryl-1-trifluoromethyl indanes in good yields (up to 99%). The predominant or exclusive formation of indanes with a trans-configuration of 1,3-diaryl groups has been observed. The reaction proceeds through an intermediate formation of the corresponding mesomeric CF3-allyl cations. A plausible reaction mechanism is discussed.

The work is focused on the design of drugs that prevent and treat Alzheimer’s disease (AD) and its complications. A series of 3-(4-aminophenyl)-coumarin derivatives designed, synthesised, fully characterised and evaluated in vitro/vivo. The biological assay experiments showed that some compounds displayed a clearly selective inhibition for acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Among all compounds, compound 4m exhibited the highest AChE inhibition with an IC50 value of 0.091 +/- 0.011 mu M and compound 4k exhibited the highest BuChE inhibition with an IC50 value of 0.559 +/- 0.017 mu M. A zebrafish behaviour analyser (Zebrobox) was used to determine the behavioural effects of the active compound on the movement distance of the aluminium chloride-induced zebrafish. Compound 4m offered a potential drug design concept for the development of therapeutic or preventive agents for AD and its complications.
