Application of gas sensors for modelling the dynamic growth of Pseudomonas in pork stored at different temperatures

Pseudomonas have a faster growth rate over other bacteria in chilled meat under aerobic conditions. A non-destructive method for modelling the dynamic growth of Pseudomonas in pork stored at different temperatures using gas sensors was presented in our work. Based on selected gas sensor data, the first-order kinetic equations (Gompertz and Logistic Functions) combined with the secondary model (Square-root Function) effectively simulated Pseudomonas growth in pork at different temperatures with R-2 and RMSE values of 0.71-0.97 and 0.27-0.84, respectively. Additionally, these models showed high accuracy with correlation coefficients greater than 0.90, in addition to several individual accuracy values. Furthermore, HS-SPME/GC-MS results demonstrated the presence of identified key volatiles in samples inoculated with Pseudomonas, including three amine compounds (mercaptamine, 1-octanamine and 1-heptadecanamine), phenol and indole. Our work showed that gas sensors are a rapid, easy and non-destructive method with acceptable feasibility in modelling the dynamic growth of spoilage microorganisms in meat.

Synthetic Studies on Dimeric Monoterpene Indole Alkaloid: (+)-Haplophytine

Since dimeric indole alkaloids possess architectural diversities and a wide range of biological activities, development of new synthetic strategies for construction of these structures has been one of the important topics in synthetic chemistry. Among these compounds, we focused on an architecturally intriguing dimeric monoterpene indole alkaloid, (+)-haplophytine, which had remained an unanswered challenge for more than a quarter century in the area of alkaloid synthesis. Our first total synthesis and the second generation synthesis of (+)-haplophytine are described. The synthesis of this dimeric compound features Ag-mediated coupling reaction between two polycyclic fragments. In addition, the characteristic diazabicyclo [3.3.1] skeleton in left segment was constructed by means of creative skeletal rearrangement including oxidation step.

Rhodium(III)-catalyzed intermolecular cyclization of anilines with sulfoxonium ylides toward indoles

Rhodium(III)-catalyzed synthesis of indole derivatives has been realized via cascade reaction of C-H alkylation/nucleophilic cyclization starting from readily available N-phenylpyridin-2-amines and sulfoxonium ylides. Notably, this transformation could smoothly proceed with high yields, good regioselectivity, and feature broad group tolerance and under redox-neutral condition to avoid external oxidant.

Synthesis of 2,3-disubstituted indoles via a tandem reaction

A strategy for the synthesis of 2,3-disubstituted indoles from 2-allyl-2-(2-nitrophenyl)cyclohexane-1,3-dione has been developed. A wide array of 2,3-disubstituted indoles were accessed in modest to good yieldsviaa tandem reduction/condensation/fragmentation/cyclization sequence. The utility of this strategy was exemplified in the formal syntheses of leucomidine A and goniomitine. The mechanism was confirmed by experiments and density functional theory (DFT) calculations. Differential fragmentation made the reaction more complicated.

Prenylated indole alkaloids and chromone derivatives from the fungus Penicillium sp SCSI0041218

Four new prenylated indole alkaloids (1-4), and four new chromone derivatives (7-10), together with six known compounds (5, 6, and 11-14), have been isolated from the mangrove sediment derived fungus Penicillium sp. SCSI0041218, cultured in the 1% NaCI PDB substrate. The structures of new compounds were determined by analysis of the NMR and MS spectroscopic data. The absolute configuration of the prenylated indole alkaloids were elucidated based on the comparison of ECDs with known analogues. The absolute configurations of the chromone derivatives were determined by time-dependent density functional theory calculations of the ECD spectra.

IntraMolecular Diels-Alder Reactions of Vinylarenes and Alkynyl Arenes (the IMDAV Reaction) (vol 53, pg 893, 2021)

This comprehensive review summarizes the published literature data concerning the intramolecular Diels-Alder reactions of vinylarenes (the IMDAV reaction) and alkynyl arenes from 1970 to 2019, and covers mainly intramolecular [4+2] cycloaddition reactions of vinyl- or acetylene-substituted furans, thiophenes, pyrroles, indoles, imidazoles, benzenes, and naphthalenes, in which the unsaturated substituent is linked directly to an arene moiety. The selected area of the Diels-Alder reaction differs from other forms of [4+2] cycloadditions due to the uniqueness of the diene fragment, which, along with an exocyclic multiple bond, includes the double bond of an aromatic or heteroaromatic nucleus in its system. Thus, during the formation of the [4+2] cycloaddition intermediate, the aromaticity of furan, thiophene and even benzene rings is broken, leading, as a rule, to the formation of heterocyclic structures rarely accessible by other methods, in contrast to the majority of intermolecular Diels-Alder reactions, with the highest degree of chemo-, regio-, and diastereoselectivity. Therefore, the IMDAV approach is often used for the synthesis of naturally occurring and bioactive molecules, which are also discussed in this review alongside other applications of this reaction. Whenever possible, we have tried to avoid examples of radical, photochemical, oxidative, precious-metal-complex-catalyzed cyclizations and other types of formal [4+2] cycloadditions, focusing on thermal Diels-Alder reactions in the first step, according to the classical mechanism. The second stage of the process, aromatization, is unique for many initial substrates, and hence considerable attention in this overview is given to the detailed description of the reaction mechanisms. 1 Introduction 2 IMDAV Reactions of Vinylfurans 2.1 Alkenes as Internal Dienophiles 2.2 Alkynes and Allenes as Internal Dienophiles 3 IMDAV Reactions of Vinylthiophenes 3.1 Alkenes as Internal Dienophiles 3.2 Alkynes as Internal Dienophiles 4 IMDAV Reactions of Vinylbenzothiophenes 5 IMDAV Reactions of Vinylpyrroles 6 IMDAV Reactions of Vinylindoles 6.1 Alkenes as Internal Dienophiles 6.2 Alkynes as Internal Dienophiles 7 IMDAV Reactions of Styrenes and Vinylnaphthalenes 7.1 Alkenes as Internal Dienophiles 7.2 Alkynes as Internal Dienophiles 7.3 Alkynes as Internal Dienophiles in Aryl Acetylenes (the Intramolecular Dehydro Diels-Alder Reaction) 8 IMDAV Reactions of Vinylimidazoles, Vinylisoxazoles and Vinylpyridines 9 Conclusion 10 Abbreviations

Palladium/Norbornene-Catalyzed C-H Alkylation/Alkyne Insertion/Indole Dearomatization Domino Reaction: Assembly of Spiroindolenine-Containing Pentacyclic Frameworks

Reported is a highly chemoselective intermolecular annulation of indole-based biaryls with bromoalkyl alkynes by using palladium/norbornene (Pd/NBE) cooperative catalysis. This reaction is realized through a sequence of Catellani-type C-H alkylation, alkyne insertion, and indole dearomatization, by forming two C(sp(2))-C(sp(3)) and one C(sp(2))-C(sp(2)) bonds in a single chemical operation, thus providing a diverse range of pentacyclic molecules, containing a spiroindolenine fragment, in good yields with excellent functional-group tolerance. Preliminary mechanistic studies reveal that C-H bond cleavage is likely involved in the rate-determining step, and the indole dearomatization might take place through an olefin coordination/insertion and -hydride elimination Heck-type pathway.
