RhII-Catalyzed beta-C(sp2)?H Alkylation of Enol Ethers, Enamides and Enecarbamates with alpha-Diazo Dicarbonyl Compounds

A RhII-catalyzed method for intermolecular alkylation of the beta-C(sp2)?H bond of enol ethers, enamides, and enecarbamates with alpha-diazo-1,3-dicarbonyl compounds is reported. The products are formed in up to 99 % yield and can be readily derivatized under a variety of conditions. By utilizing a combination of experimental and computational studies, the presumptive addition?elimination reaction mechanism was investigated and found to proceed under thermodynamic control at higher temperature. The acquired fundamental knowledge was translated into a strategic reaction design and yielded the first example of the beta-C?H functionalizations of acyclic enol ethers using alpha-diazo-1,3-dicarbonyl compounds.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 73286-71-2, help many people in the next few years.Computed Properties of C9H15NO2

Br¡ãnsted acid catalyzed proto-functionalization of enecarbamates and enamides: A convenient route to N,O-acetals

N,O-acetals are important structures found in many bioactive natural products, and this unique organic functional group can serve as a useful synthetic precursor to the unstable N-acylimines. In this paper, a convenient route to synthesize N-carbamoyl-N,O-acetals and N-acyl-N,O-acetals from enecarbamates and enamides in the presence of alcohols as the solvents and nucleophile sources under Br¡ãnsted acid conditions was reported. This strategy could be used to prepare various N,O-acetals from a range of enecarbamates and enamides with light alcohols, and the products are obtained in good yields (52?98%).

Design, synthesis, and biological evaluation of N-carboxyphenylpyrrole derivatives as potent HIV fusion inhibitors targeting gp41

On the basis of the structures of small-molecule hits targeting the HIV-1 gp41, N-(4-carboxy-3-hydroxy)phenyl-2,5-dimethylpyrrole (2, NB-2), and N-(3-carboxy-4-chloro)phenylpyrrole (A1, NB-64), 42 N-carboxyphenylpyrrole derivatives in two categories (A and B series) were designed and synthesized. We found that 11 compounds exhibited promising anti-HIV-1 activity at micromolar level and their antiviral activity was correlated with their inhibitory activity on gp41 six-helix bundle formation, suggesting that these compounds block HIV fusion and entry by disrupting gp41 core formation. The structure-activity relationship and molecular docking analysis revealed that the carboxyl group could interact with either Arg579 or Lys574 to form salt bridges and two methyl groups on the pyrrole ring were favorable for interaction with the residues in gp41 pocket. The most active compound, N-(3-carboxy-4-hydroxy)phenyl-2,5-dimethylpyrrole (A12), partially occupied the deep hydrophobic pocket, suggesting that enlarging the molecular size of A12 could improve its binding affinity and anti-HIV-1 activity for further development as a small-molecule HIV fusion and entry inhibitor.

Bismaleimide monomers with various structures and polyaspartimides

A series of bismaleimide monomers with various structures were synthesized by the reaction of bisphenols or diamines with 3 or 4- maleimidobenzoyl chloride. The reaction of these bismaleimides with aromatic diamines (Michael addition) yielded polyaspartimides. The monomers and polymers were characterized by FTIR and ‘H-NMR spectroscopy and elemental analysis. Thermal characterization of monomers and polymers was accomplished by differential scanning calorimetry and dynamic thermogravimetric analysis. Some of the mechanical properties of the films based on these polymers were studied.

Alkaloids induce programmed cell death in bloodstream forms of trypanosomes (Trypanosoma b. brucei)

The potential induction of a programmed cell death (PCD) in Trypanosoma b. brucei by 55 alkaloids of the quinoline, quinolizidine, isoquinoline, indole, terpene, tropane, steroid, and piperidine type was studied by measuring DNA fragmentation and changes in mitochondrial membrane potential. For comparison, the induction of apoptosis by the same alkaloids in human leukemia cells (Jurkat APO-S) was tested. Several alkaloids of the isoquinoline, quinoline, indole and steroidal type (berberine, chelerythrine, emetine, sanguinarine, quinine, ajmalicine, ergotamine, harmine, vinblastine, vincristine, colchicine, chaconine, demissidine and veratridine) induced programmed cell death, whereas quinolizidine, tropane, terpene and piperidine alkaloids were mostly inactive. Effective PCD induction (EC50 below 10 muM) was caused in T. brucei by chelerythrine, emetine, sanguinarine, and chaconine. The active alkaloids can be characterized by their general property to inhibit protein biosynthesis, to intercalate DNA, to disturb membrane fluidity or to inhibit microtubule formation.
