A novel approach for the synthesis of dipyrrolyl alkanols and dipyrrolyl alkylamines

Pyrrole reacts smoothly with cyclic enol ethers and enecarbamates in the presence of 5 mol% indium tribromide or 10 mol% indium trichloride under mild and convenient conditions to afford the corresponding bis-pyrrolyl-alkanols and alkyl amines, respectively, in high yields with high selectivity.

Batch versus flow photochemistry: A revealing comparison of yield and productivity

The use of flow photochemistry and its apparent superiority over batch has been reported by a number of groups in recent years. To rigorously determine whether flow does indeed have an advantage over batch, a broad range of synthetic photochemical transformations were optimized in both reactor modes and their yields and productivities compared. Surprisingly, yields were essentially identical in all comparative cases. Even more revealing was the observation that the productivity of flow reactors varied very little to that of their batch counterparts when the key reaction parameters were matched. Those with a single layer of fluorinated ethylene propylene (FEP) had an average productivity 20% lower than that of batch, whereas three-layer reactors were 20% more productive. Finally, the utility of flow chemistry was demonstrated in the scale-up of the ringopening reaction of a potentially explosive [1.1.1] propellane with butane-2,3-dione.

Probing the Peroxycarbenium [3+2] Cycloaddition Reactions with 1,2-Disubstituted Ethylenes: Results and Insights

The causes for the title reaction to be limited to only the alkenes with an unsubstituted terminal alkenic carbon were explored. In some ?failed? cases the cycloaddition products actually formed but rearranged concurrently. An oxygen atom or a N-Boc (Boc=tert-butyloxycarbonyl) group at the double bond was proven essential for acquisition of intact [3+2] cycloaddition products from 1,2-disubstituted ethylenes.

NIR induced self-healing electrical conductivity polyurethane/graphene nanocomposites based on Diels?Alder reaction

In this work, a crosslinker terminal maleimide groups (EDM) has been synthesized and was used in reactions with the pendant furan groups of polyurethane (PUE) to prepare the self-healing electrically conductive composites based on Diels-Alder reaction, and Ag nanowires (AgNWs) as the conductive network inlaid in the surface layer of the polymer matrix layer. Inspired by the graphene-based materials for its versatility in both material and chemical properties, and we present a new synthetic strategy for the preparation of functional graphene nanosheets with DA group that can be employed in the self-healing polyurethane system. To our best knowledge, it hasn’t been reported yet the structure graphene oxide materials (rmGO) in any systems. The rmGO served as fillers to reinforce the composites and would participated in the DA reactions. The excellent NIR light-induced self-healing property of prepared composites was realized through the photo-thermal effect of rmGO. The composite is capable of both structural and electrical healing via NIR irradiation. The injured samples can be locally repaired with high precision and efficiency without an obvious influence on those uninjured parts. The underlying polymer matrix can reform via the dynamic dissociation/recombination of Diels-Alder bonds to bring the separated areas of the AgNWs layer into contact to restore the conductivity. The NIR light-induced self-healing electrically conductive composites have wide potential for many fields, e.g., soft robots, flexible devices, and health-monitoring.

A sensitive and selective liquid chromatography-tandem mass spectrometry method for simultaneous determination of five isoquinoline alkaloids from Chelidonium majus L. in rat plasma and its application to a pharmacokinetic study

Chelidonium majus L. is one of the most important medicinal plants of the family Papaveraceae. Its pharmacological effects have been primarily attributed to the presence of a number of alkaloids. In the present study, a sensitive and selective liquid chromatography-tandem mass spectrometry method for simultaneous determination of five isoquinoline alkaloids from Chelidonium majus L. was developed and validated. The analytes (protopine, chelidonine, coptisine, sanguinarine and chelerythrine), together with the internal standard (palmatine), were extracted from acidified rat plasma with ethyl acetate-dichloromethane (4:1, v/v). Chromatographic separation was carried out on a Diamonsil C18 column with an isocratic mobile phase consisting of acetonitrile and water (adjusted to pH 2.3 with formic acid) (30:70, v/v) at a flow rate of 0.4 ml/min. Mass spectrometric detection was performed by selected reaction monitoring mode via electrospray ionization source operating in positive ionization mode. The assay exhibited good linearity (r ? 0.9933) for all the analytes. The lower limits of quantification were 0.197-1.27 ng/ml using only 50 mul of plasma sample. The intra- and inter-day precisions were less than 11.9%, and the accuracy was between -6.3% and 9.3%. The method was successfully applied to the pharmacokinetic study of the five alkaloids in rats after intragastric administration of Chelidonium majus L. extract.

A bacterial quorum-sensing precursor induces mortality in the marine coccolithophore, Emiliania huxleyi

Interactions between phytoplankton and bacteria play a central role in mediating biogeochemical cycling and food web structure in the ocean. However, deciphering the chemical drivers of these interspecies interactions remains challenging. Here, we report the isolation of 2-heptyl-4-quinolone (HHQ), released by Pseudoalteromonas piscicida, a marine gamma-proteobacteria previously reported to induce phytoplankton mortality through a hitherto unknown algicidal mechanism. HHQ functions as both an antibiotic and a bacterial signaling molecule in cell-cell communication in clinical infection models. Co-culture of the bloom-forming coccolithophore, Emiliania huxleyi with both live P. piscicida and cell-free filtrates caused a significant decrease in algal growth. Investigations of the P. piscicida exometabolome revealed HHQ, at nanomolar concentrations, induced mortality in three strains of E. huxleyi. Mortality of E. huxleyi in response to HHQ occurred slowly, implying static growth rather than a singular loss event (e.g., rapid cell lysis). In contrast, the marine chlorophyte, Dunaliella tertiolecta and diatom, Phaeodactylum tricornutum were unaffected by HHQ exposures. These results suggest that HHQ mediates the type of inter-domain interactions that cause shifts in phytoplankton population dynamics. These chemically mediated interactions, and other like it, ultimately influence large-scale oceanographic processes.
