Palladium(ii)-catalyzed three-component tandem reactions: synthesis of multiply substituted quinolines

The three-component tandem reaction of 2-aminobenzonitriles, arylboronic acids and ketones allowing the synthesis of polysubstitution quinolines is reported. This strategy presents a practical, efficient, one-pot procedure that delivers functional quinolines in moderate to good yields with high functional group tolerance. To enrich the synthetic applications in accessing diverse quinolines, a new method for the introduction of halogen substituents into target products has been developed as well, which shows potential for further synthetic elaborations.

Improved Synthetic Route to C-Ring Ester-Functionalized Prodigiosenes

An efficient, optimized, and scalable process for the synthesis of C-ring ester-functionalized prodigiosenes has been developed by (i) exploiting a silylative Mukaiyama aldol strategy for the condensation of alkyl 5-formyl-2,4-dimethylpyrrole-3-carboxylate and 4-methoxy-3-pyrrolin-2-one to form the corresponding ester-functionalized dipyrrinone analogues, and (ii) developing a facile synthesis of stable bromodipyrrin analogues for the use in formal Suzuki coupling reactions. The process was applied to the synthesis of three C-ring ester-functionalized prodigiosenes in multigram scales (up to 6.5 g prodigiosene free-base) with useful yields (35-56% overall yields over three steps starting from the 2-formyl pyrroles).

Effects of graphene surface functionalities towards controlled reinforcement of a lignin based renewable thermoplastic rubber

This report describes methods to enhance mechanical properties of a renewable thermoplastic rubber by incorporating functional graphene platelets into an equal-mass mixture of lignin, a feedstock from plant biomass, and a nitrile-butadiene rubber having 41 mol % acrylonitrile content (NBR41) that form a nanocomposite. Not all lignins yield mechanically strong material when they are combined with NBR41, and thus, limit its use for such rubbery products. Here, we evaluate different graphene oxides (GO) and reduced graphene oxides (rGO) dry-powders with different surface areas, functionality, and wettability in the synthesis of performance-enhanced nanocomposites of soft lignin/NBR41 matrix via a solvent-free, high shear reactive process. High surface area GO (HSGO) platelets with strong hydrophilicity exhibit good dispersion in the multiphase lignin/NBR41 composites with lignin dispersion varying from 200 to 2000 nm, resulting in superior reinforcement over other graphene derivatives. The addition of 1-4 wt % HSGO increased the tensile stress of the lignin/NBR41 thermoplastic rubber matrix by 60-160% (15-24 MPa) and the modulus by 200-700% (60-140 MPa). Scanning electron microscopy and small angle X-ray scattering results show that the well-dispersed HSGO platelets effectively disrupt the lignin-rich aggregates in NBR41 matrix, resulting in both strength and stiffness enhancements in the formed nanocomposites. This report on performance enhancement of lignin-based renewable polymers via the production of nanocomposite would increase potential for `finding the value of lignin’-a grand challenge associated with modern biorefineries.

2-(3-pyrrolin-1-yl)-1,4-naphthoquinones: Photoactivated alkylating agents

The preparation of 2-(3-pyrrolin-1-yl)-1,4-naphthoquinones and a study of their use as photoactivated alkylating agents is reported. The title compounds were easily synthesized by conjugate addition of the corresponding 3-pyrrolines to various naphthoquinones. Upon exposure to ambient room light, the compounds undergo an internal redox reaction to form 2-(pyrrol-1-yl)-1,4-hydroquinones, which are activated for nucleophilic addition by an S(N)1 azafulvene mechanism. Control experiments demonstrated that the redox reaction is triggered by light and that the nucleophilic addition does not proceed before this activation occurs. ((C) Wiley-VCH Verlag GmbH & Co.

Involvement of esterase in phytotoxicity of a new pyrrolinone compound, methyl 1-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-4-methyl-2-oxo-3-phenyl-1H-pyrrole-3-carboxylate, to early watergrass (Echinochloa oryzicola) and rice (Oryza sativa)

A new pyrrolinone compound, methyl 1-[1-(3,5-dichlorophenyl)-1-methyl ethyl] -2,3-dihydro-4-methyl-2-oxo-3 phenyl-1H-pyrrole-3-carboxylate (PC-1), has herbicidal activity against early watergrass (Echinochloa oryzicola). This compound showed good selectivity between rice (Oryza sativa) and early watergrass due to the introduction of a methoxycarbonyl group into the Pyrrolinone structure. To elucidate the mechanism of PC-Is phytotoxicity, the effects of esterase inhibitors (triphenyl phosphate, tributyl phosphate and fenitrothion) and a cytochrome P450 monooxygenase inhibitor (1-aminobenzotriazole) on the actions of PC-I were examined. Triphenyl phosphate and fenitrothion reduced the phytotoxicity of PC-1 in hydroponics and greenhouse tests. Porcine liver esterase converted PC-1 to 1-[1-(3,5-dichiorophenyl)-1-methylethyl]-4-methyl-3-phenyl-3-pyrrolin-2-one (PC-2) and this reaction was inhibited by triphenyl phosphate. The PC-2 content of early watergrass treated with PG I was 4 times that of rice. These results suggest that PG I is a prodrug and is converted to PC-2 by esterase, and that the amount of PC-2 produced in PC-1-treated plants is related to the sensitivity of early watergrass and rice to PC-1.

Z-Selective alpha-Arylation of alpha,beta-Unsaturated Nitriles via [3,3]-Sigmatropic Rearrangement

The Morita-Baylis-Hillman (MBH) reaction and [3, 3]-sigmatropic rearrangement are two paradigms in organic synthesis. We have merged the two types of reactions to achieve [3,3]-rearrangement of aryl sulfoxides with alpha,beta-unsaturated nitriles. The reaction was achieved by sequentially treating both coupling partners with electrophilic activator (Tf2O) and base, offering an effective approach to prepare synthetically versatile alpha-aryl alpha,beta-unsaturated nitriles with Z-selectivity through direct alpha-C-H arylation of unmodified alpha,beta-unsaturated nitriles. The control experiments and DFT calculations support a four-stage reaction sequence, including the assembly of Tf2O activated aryl sulfoxide with alpha,beta-unsaturated nitrile, MBH-like Lewis base addition, [3,3]-rearrangement, and E1cB-elimination. Among these stages, the Lewis base addition is diastereoselective and E1cB-elimination is cis-selective, which could account for the remarkable Z-selectivity of the reaction.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 95-45-4, you can contact me at any time and look forward to more communication. HPLC of Formula: https://www.ambeed.com/products/95-45-4.html.
