Organocatalytic enantioselective allylic alkylation of alpha-aryl gamma-lactones: an approach to densely functionalized quaternary stereocentres

The asymmetric allylic alkylation (AAA) of alpha-aryl gamma-lactones involving the activation of Morita-Baylis-Hillman (MBH) carbonates by an original chiral Lewis base is reported. A wide range of gamma-lactones bearing a quaternary stereocentre was thus obtained in both high yields and high enantiomeric ratios. The direct alkylation by MBH alcohol usingin situactivation has been also established. Additionally synthetically useful functional transformations of groups surrounding the quaternary stereocentre have been performed.

A series of novel cell membrane fluorescent probes based on oxazolopyridine unit

Fluorescent cell membrane probes (1a-d) were designed from bioactive oxazolo [4,5-b]pyridine unit. The probes were connected by oxazolo [4,5-b]pyridine and benzofuran (1a), triphenyl (1b), coumarin (1c), diethylaminobenzene (1d), respectively, with a double bond. The optical properties of 1a-d with different solvents were tested, they had obvious solvatochromism in different polar solvents, Large stokes shifts (63-204 nm) and significant fluorescent enhancement in large multilamellar vesicles (MLV). After 6 h of continuous illumination, the remaining absorption of the probes was 81-97%. The cytotoxicity test indicated that the survival rate of HeLa and L929 cells was 94-119% after co-cultured with probes 1a-d for 6 h. Laser confocal experiments further illustrated that the probes could quickly (<1 min) combine with the cell membrane. Among them, probe 1a worked in the green channel, while probes 1b, 1c and 1d employed in the red channel. Moreover, the retention time of probes 1a and 1c on cell membrane was found to 2-3 h.

Fungal mycotoxin penisuloxazin A, a novel C-terminal Hsp90 inhibitor and characteristics of its analogues on Hsp90 function related to binding sites

Hsp90 is a promising drug target for cancer therapy. However, toxicity and moderate effect are limitations of current inhibitors owing to broad protein degradation. The fungal mycotoxin penisuloxazin A (PNSA) belongs to a new epipolythiodiketopiperazines (ETPs) possessing a rare 3H-spiro[benzofuran-2,2′-piperazine] ring system. PNSA bound to cysteine residues C572/C598 of CT-Hsp90 with disulfide bonds and inhibits Hsp90 activity, resulting in apoptosis and growth inhibition of HCT116 cells in vitro and in vivo. We identified that analogues PEN-A and HDN-1 bound to C572/C597 and C572 of CT-Hsp90 alpha respectively, with binding pattern very similar to PNSA. These ETPs exhibited different effects on ATPase activity, dimerization formation and selectivity on client protein of Hsp90, indicating client recognition of Hsp90 can be exactly regulated by different sites of Hsp90. Our findings not only offer new chemotypes for anticancer drug development, but also help to better understand biological function of Hsp90 for exploring inhibitor with some client protein bias.

Cut and sew: benzofuran-ring-opening enabled cyclopentenone ring formation

A facile approach to the fully substituted cyclopentenones involving an unprecedented benzofuran-ring-opening is described. The cleavage of a benzofuran endocyclic C2-O bond proceeded smoothly in the absence of any transition metal catalyst or highly reactive organometallic reagent. Such benzofuran-ring-opening is delicately incorporated into an acid-catalyzed cascade process, orchestrating a novel synthetic strategy for complex cyclopentenones with excellent yields and diastereoselectivities.

One-Pot Two-Step Chemoenzymatic Cascade for the Synthesis of a Bis-benzofuran Derivative

Chemoenzymatic cascades enable reactions with the high productivity of chemocatalysts and high selectivity of enzymes. Nevertheless, the combination of these different fields of catalysis is prone to mutual deactivation of metal- and biocatalysts. In this study, a one-pot sequential two-step catalytic cascade reaction was successfully implemented for the synthesis of a methylene-bridged bis(2-substituted benzofuran). In the first step, a palladium-free Sonogashira reaction is used for the synthesis of a benzofuran derivative. In the subsequent step, the formed 2-substituted benzofuran is hydroxylated by the monooxygenase P450 BM3 variant (A74S-F87V-L188Q) and undergoes further elimination reactions. The study proofs that combination of Cu scorpionate catalyzed Sonogashira cross-coupling and P450 mediated oxidation is possible and results in up to 84 % yield of the final product. The oxidation reaction is boosted by capturing inhibiting reaction components.

In comparison to BDTT-TR with centrosymmetric BDT as the central unit, TBFT-TR with asymmetric TBF as the central unit shows red-shifted absorption, higher charge-carrier mobility and better charge pathway in blend films. The power conversion efficiency (PCE) of the all-SMOSCs based on TBFT-TR:Y6 reaches 14.03% with a higher short-circuit current density of 24.59 mA cm(-2) and a higher fill factor of 72.78% compared to the BDTT-TR:Y6 system.

A comparative study on the essential oil composition and antibacterial activities of different organs of wild growing Paeonia daurica subsp. tomentosa from Iran

Paeonia daurica subsp. tomentosa (Lomakin) D.Y.Hong is an herbaceous perennial and flowering plant from the Paeoniaceae family. In this research, the roots, stems, leaves and fruits of P. daurica subsp. tomentosa were investigated for a comparative identification of essential oil composition. The essential oils constituents were identified by GC/MS and then compared. The study leads to the identification of 31, 57, 66, and 57 components in the essential oils obtained from the roots, stems, leaves and fruits, respectively. These chemicals make up more than 99% of the essential oil. Some of the identified compounds (alpha-Pinene, 4-ethyloctane, 5-methylnonane, benzaldehyde, myrtanal, 4,7-dimethyl benzofuran, n-decane, cuminaldehyde, cis-p-mentha-6,8-diene-2-ol, salicylaldehyde, tetradecane, tetradecanal, and n-tricosane) occurred in all parts of the plant. The existence of compounds such as cembrene (1.1%), 13-epi-manool (1.5%), 2-hydroxy methyl benzoate (10.1%), and tridecanal (0.7%), however, were confirmed exclusively in the fruit, stem, root, and leaf, respectively. The antibacterial activities (MIC) of the oils obtained from the four studied Paeonia parts against Escherichia coli and Staphylococcus aureus was studied. Staphylococcus aureus was the most sensitive microorganism to the oil obtained from the fruits of P. daurica subsp. tomentosa with the value of 0.04 +/- 0.005 mg mL(-1).

alpha-Lithiobenzyloxy as a Directed Metalation Group in ortho-Lithiation Reactions

The alpha-lithiobenzyloxy group, easily generated from aryl benzyl ethers by selective alpha-lithiation with t-BuLi at low temperature, behaves as a directed metalation group (DMG) providing a direct access to o-lithiophenyl alpha-lithiobenzyl ethers. This ortho-directing effect is reinforced in substrates bearing an additional methoxy group at the meta position. The generated dianions can be reacted with a selection of electrophiles including carboxylic esters and dihalosilanes or germanes, which afford interesting benzofuran, sila(germa)dihydrobenzofuran, and silachroman derivatives from simple aryl benzyl ethers.
