Isomerization of N-Allylamides and -imides to Aliphatic Enamides by Iron, Rhodium, and Ruthenium Complexes

Substituted aliphatic N-propenylamides and -imides are readily sythesized from N-allylamides by double bond migration induced by rhodium or ruthenium hydrides.N-Propenylimides can be prepared from allylimides only in the presence of iron pentacarbonyl.

Highly selective bisphosphine ligands for asymmetric hydroformylation of heterocyclic olefins

The bisphosphine ligand 1c is highly efficient and selective for the asymmetric hydroformylation (AHF) of dihydrofuran and pyrrolines. The AHF of 2,3-dihydrofuran yielded the 2-carbaldehyde in up to 93% ee. The remarkable highest regioselectivity of 2,5-dihydrofuran was obtained to date up to 499 beta-isomer/alpha-isomer with ligand 1c. Furthermore, the highest 96% and 92% ee values were accomplished using the same catalytic system in the AHF of N-Boc pyrroline 11 and 14.

Highly beta-regioselective Friedel-Crafts aminoalkylation of pyrroles with cyclic perfluoroalkylated imines

A Friedel-Crafts-type alkylation reaction was studied between various pyrroles and alpha-polyfluoroalkylated cyclic imines that were activated by Lewis acids. The reaction proceeded under mild conditions and provided a high yielding synthesis of alpha-CF3-substituted pyrrolidines and piperidines as well as seven-membered analogues that contained a pyrrole ring. The unpredictably high beta-selectivity for the aminoalkylation of both 1H-pyrrole and N-substituted pyrrole was observed as a result of a thermodynamically-controlled electrophilic substitution reaction. The computational data are in full agreement with the experimental results, which confirmed the observed regioselectivity as a result of the lower energy of the beta-substituted pyrroles that contain alpha-trifluoromethyl-substituted pyrrolidine, piperidine, and azepane rings. Trifluoromethyl-substituted cyclic imines were activated by various Lewis acids and underwent a reaction with pyrrole derivatives. An unpredictable beta-selectivity was observed. The regioselectivity of the aminoalkylation was explained by computation data, which also confirmed the isomerization of the alpha isomer into the beta isomer. Copyright

Anti-Stokes Stress Sensing: Mechanochemical Activation of Triplet?Triplet Annihilation Photon Upconversion

The development of methods to detect damage in macromolecular materials is of paramount importance to understand their mechanical failure and the structure?property relationships of polymers. Mechanofluorophores are useful and sensitive molecular motifs for this purpose. However, to date, tailoring of their optical properties remains challenging and correlating emission intensity to force induced material damage and the respective events on the molecular level is complicated by intrinsic limitations of fluorescence and its detection techniques. Now, this is tackled by developing the first stress-sensing motif that relies on photon upconversion. By combining the Diels?Alder adduct of a pi-extended anthracene with the porphyrin-based triplet sensitizer PtOEP in polymers, triplet?triplet annihilation photon upconversion of green to blue light is mechanochemically activated in solution as well as in the solid state.

Dimeric Drug Polymeric Micelles with Acid-Active Tumor Targeting and FRET-Traceable Drug Release

Trans-activating transcriptional activator (TAT), a cell-penetrating peptide, is extensively used for facilitating cellular uptake and nuclear targeting of drug delivery systems. However, the positively charged TAT peptide strongly interacts with serum components and undergoes substantial phagocytosis by the reticuloendothelial system, causing a short blood circulation in vivo. In this work, an acid-active tumor targeting nanoplatform DA-TAT-PECL is developed to inhibit the nonspecific interactions of TAT in the bloodstream. 2,3-dimethylmaleic anhydride (DA) is used to convert the TAT’s amines to carboxylic acid; the resulting DA-TAT is conjugated to poly(ethylene glycol)-poly(epsilon-caprolactone) (PEG-PCL, PECL) to get DA-TAT-PECL. After self-assembly into polymeric micelles, they are capable of circulating in the physiological condition for a long time and promoting cell penetration upon accumulation at the tumor site and deshielding the DA group. Moreover, camptothecin (CPT) is used as the anticancer drug and modified into a dimer (CPT)2-ss-Mal, in which two CPT molecules are connected by a reduction-labile maleimide thioether bond. The Foerster resonance energy transfer signal between CPT and maleimide thioether bond is monitored to visualize the drug release process, and effective targeted delivery of antitumor drugs is demonstrated. This pH/reduction dual-responsive micelle system provides a new platform for high fidelity cancer therapy.

New isoquinoline alkaloid hypepontine (1) together with a five known compounds, were identified in Hypecoum ponticum Velen, the partial synonym of Hypecoum procumbens L. The structure of the new substance was elucidated based on spectroscopic evidence. The tertiary and quaternary alkaloid mixtures as well as the isolated alkaloids were evaluated for their antibacterial and antifungal activity. The result revealed that the crude alkaloid mixture containing quaternary isoquinoline alkaloids showed potent antifungal and antibacterial activity.

Microwave-assisted synthesis and structure-activity relationships of neuroactive pyrazolo[3,4-b]pyrrolo[3,4-d]pyridine derivatives

We described herein the optimization of the synthetic methodology exploited to obtain the pyrazolo[3,4-b]pyrrolo[3,4-d]pyridine sedative prototype 1a and novel analogues designed by successive molecular simplifications. By applying microwave irradiation during the hetero Diels-Alder key-step to obtain the heterotricyclic scaffold, under solvent-free conditions, we were able to obtain the desired compounds in drastically shorter times and better yields. Additionally, in vivo evaluation of the sedative effects of these heterocyclic derivatives showed that 1a and the novel structurally-related analogue 1e were the most efficient compounds to impair the locomotor activity in mice at the dose of 10 mumol/kg.

Organotin complexes containing carboxylate ligands with maleimide and naphthalimide derived partial structures: TrxR inhibition, cytotoxicity and activity in resistant cancer cells

Di-n-butyltin(IV) carboxylate and tri-n-butyltin(IV) carboxylate derivatives have demonstrated strong cytotoxic effects in different types of tumor cells. Complexes with carboxylate ligands that contain maleimide and naphthalimide derived partial structures were synthesized, characterized and investigated for inhibition of the tumor-relevant enzyme thioredoxin reductase and antiproliferative effects in cancer cells. The complexes were moderate inhibitors of thioredoxin reductase with activities in the micromolar range and triggered strong cytotoxic effects in MCF-7 breast cancer and HT-29 colon carcinoma cells. Interestingly, selected complexes were highly active in vincristine and daunorubicin resistant Nalm-6 cells.
