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.

Widely targeted metabolic analysis revealed the changed pigmentation and bioactive compounds in the ripening Berchemia floribunda (Wall.) Brongn. fruit

Berchemia plants were important materials for Chinese traditional medicines due to their special secondary metabolites. Unlike the root, stem and leaf tissues, Berchemia floribunda (Wall.) Brongn. fruit was lacked of systematic metabolic investigation. Biochemical analysis found that the total flavonoid and total phenolic content of Berchemia fruit pulp showed a peak value at red ripe stage, and then decreased, but the total anthocyanin content sharply increased along with the coloration. By widely targeted metabolomic analysis, 644 metabolites were identified and categorized into 23 groups mainly including flavonoid, organic acids, amino acids, lipids, phenylpropanoid, nucleotides, alkaloids, carbohydrates, alcohols, anthocyanins & proanthocyanidins, vitamins, terpenes, polyphenols, phenolamides, quinones, indole derivatives, and sterides. Among them, 111 metabolites and 123 metabolites respectively showed up- and down-regulation from break stage to full mature. KEGG enrichment analysis indicated that active secondary metabolism such as biosynthesis of phenylpropanoids, flavonoid, and alkaloids happened during Berchemia fruit ripening. More importantly, Cyanidin-3-O-galactoside and other 3 cyanidins were found to be the predominant pigments in mature Berchemia fruit and increased cyanidins and pelargonidins but decreased anthocyanins might be contributed to the purple pigmentation of Berchemia fruit. Interestingly, 29 pharmaceutical compounds previously reported in other Berchemia tissues were also detected in ripening Berchemia fruit pulp: 8 flavonoid, 2 quinones & sucrose showed up-regulated accumulation while 6 polyphenols, 5 flavonoid, 3 phenylpropanoid, 2 organic acids, 1 quinones and beta-sitosterol showed down-regulated accumulation In conclusion, our first comprehensive metabolic fingerprint will promote the further study of B. floribunda fruit and its medical and food application.

Annihilation Delayed Fluorescence of Indole and Its Derivatives in Aqueous Solution

Spectral and kinetic characteristics of annihilation delayed fluorescence (ADF) of indole and its derivatives (5-methylindole, N-methylindole) were measured in aqueous solutions at room temperature. ADF spectra of indole and 5-methylindole consisted of two bands with wavelength maxima at 350 and 425 nm for indole and 350 and 390 nm for 5-methylindole. The short-wavelength band was due to ADF of monomers and coincided with the fast fluorescence spectrum. The long-wavelength band was attributed to ADF of excimers, the excited singlet states of which were populated by annihilation of triplet excimers. Triplet states of excimers were formed by collisions of molecules in triplet and ground states. The ADF spectrum of N-methylindole consisted of only the short-wavelength ADF band of monomers (lambda = 352 nm). Lifetimes of monomer and excimer triplet states were estimated from the ADF kinetics.

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

Structural background of fast nonradiative deexcitation of benzo [cd]indole polymethine dyes

The electronic structure of a series of benzo [cd] indole-based merocyanines and cationic polymethine dyes has been analyzed in both the ground and fluorescent states using the DFT and TD-DFT computations. The obtained data has shown the marked difference between the benzo[cd]indole dyes and those based on such typical heterocyclic cores as indole and benzimidazole. Namely, in the former, the frontier MOs have much greater coefficients at the end group(s), which leads to an enhancement of vibronic interactions in the long-wavelength absorption and fluorescence transitions. This effect seems to be the major cause of the low fluorescence lifetimes and fluorescence quantum yields of benzo[cd]indole dyes.

A novel approach to efficient degradation of indole using co-immobilized horseradish peroxidase-syringaldehyde as biocatalyst

Biocatalytic degradation technology has received a great deal of attention in water treatment because of its advantages of high efficiency, environmental friendliness, and no secondary pollution. Herein, for the first time, horseradish peroxidase and mediator syringaldehyde were co-immobilized into functionalized calcium alginate composite beads grafted with glycidyl methacrylate and dopamine. The resultant biocatalyst of the co-immobilized horseradish peroxidase-syringaldehyde system has displayed excellent catalytic performance to degrade indole in water. The degradation rate of 100% was achieved in the presence of hydrogen peroxide even if the indole concentration was changing from 25 mg/L to 500 mg/L. If only the free enzyme was used under the identical water treatment conditions, the degradation of indole could hardly be observed even when the concentration of indole is low at 25 mg/L. This was attributed to the effective co-immobilization of the enzyme and the mediator so that the catalytic activity of horseradish peroxidase and the synergistic catalytic action of syringaldehyde could be fully developed. Furthermore, while the spherical catalyst was operated in succession and reused for four cycles in 50 mg/L indole solution, the degradation rate remained 91.8% due to its considerable reusability. This research demonstrated and provided a novel biocatalytic approach to degrade indole in water by the co-immobilized horseradish peroxidase-syringaldehyde system as biocatalyst.
