Ruiz-Moyano, Santiago published the artcileSelection and application of antifungal VOCs-producing yeasts as biocontrol agents of grey mould in fruits, Related Products of isoquinoline, the main research area is antifungal volatile compound yeast gray mold fruit; Antifungal volatile compounds; Botrytis cinerea; Cherry; Postharvest; Strawberry.

Rotting caused by gray mold (Botrytis cinerea) is a concerning disease for numerous crops both pre- and postharvest stages. Application of antagonistic yeasts is a promising strategy for controlling gray mold incidence which could mitigate undesirable consequences of using synthetic fungicides. In this work, a screening for detection of yeasts isolated from figs producers of antifungal volatile organic compounds (VOCs) were performed by confrontation in double dishes systems. Eleven out of 34 yeasts confronted reduced B. cinerea growth parameter in vitro. This reduction was correlated (p ≤ 0.050) with the production of 10 volatile compounds: two acids (acetic acid and octanoic acid), 7 esters (Et propionate, n-Pr acetate, Iso-Bu acetate, 2-methylbutyl acetate, furfuryl acetate, phenylmethyl acetate, 2-phenylethyl acetate) and one ketone (Heptan-2-one). In bases on in vitro assay, Hanseniaspora uvarum 793 was applied to in vivo assays with strawberries and cherries. The reduction of incidence of B. cinerea in strawberries at 7°C and 25°C was 54.9 and 72.1% after 6 and 3 days, resp. The reduction of incidence of B. cinerea in cherries at 7°C and 25°C was 48.9 and 45.6% after 5 and 4 days, resp. These results showed that VOCs produced by Hanseniaspora uvarum 793 are effective in the control of incidence of Botrytis cinerea in fruits, being a potential alternative to chem. fungicide.

Marchetti, Mauro published the artcileAqueous biphasic hydrogenations catalyzed by rhodium and iridium complexes modified with human serum albumin, SDS of cas: 1205-17-0, the main research area is biphasic hydrogenations catalysis rhodium iridium complex; catalyst human serum albumin unsaturated aldehyde.

Water soluble complexes derived from the interaction between Rh(CO)2(acac) and [Ir(COD)Cl]2, resp., with human serum albumin (HSA), were employed in the aqueous biphasic hydrogenation of α,β-unsaturated compounds as 2-cyclohexen-1-one (I), 2-butenal (V), 3-phenyl-2-propenal (IX) and 3-aryl-2-methyl-2-propenals (XIII and XVII). Both catalytic systems Rh/HSA and Ir/HSA showed to be very active in the hydrogenation of ketone I even at low temperature and hydrogen pressure; in particular, the rhodium based catalyst showed to be very selective affording exclusively cyclohexanone (II). The α,β-unsaturated aldehydes investigated required higher temperature (up to 60°) and pressure (5 MPa) to obtain good conversions. In this case Rh/HSA resulted to be more active than Ir based catalyst. In all cases both Rh/HSA and Ir/HSA were easily recycled without significant loss of activity.

Pokluda, Adam published the artcileRobust Photocatalytic Method Using Ethylene-Bridged Flavinium Salts for the Aerobic Oxidation of Unactivated Benzylic Substrates, Formula: C2H6N2O, the main research area is ethylene bridged flavinium salt photoredox catalyst preparation fluorescence; benzyl ethylene bridged flavinium salt photocatalyst aerobic oxidation; aryl ketone preparation.

A series of ethylene-bridged flavinium salts I (R1, R2 = H, OMe, CF3, Cl; R1R2 = OCH2O; R3 = H, Me, n-octyl) has been synthesized and their photochem. and electrochem. properties have been studied. Out of these compounds, 7,8-dimethoxy-3-methyl-1,10-ethylenealloxazinium chloride I [R1 = R2 = MeO; R3 = Me; (II)] was found to be a superior photooxidation catalyst. The flavinium salt II proved to be robust enough for practical applications in benzylic oxidations/oxygenations, which was demonstrated using a series of substrates with high oxidation potential, i.e., 1-phenylethanol, ethylbenzene, diphenylmethane and diphenylmethanol derivatives substituted with electron-withdrawing groups (Cl or CF3). The unique capabilities of the compound II can be attributed to its high photostability and participation via a relatively long-lived singlet excited state, which was confirmed using spectroscopic studies, electrochem. measurements and TD-DFT calculations This allows the maximum use of the oxidation power of the compound II, which was given by its singlet excited state reduction potential of +2.4 V. This compound can be used as an alternative photocatalyst for even more difficult substrates.

The first palladium-catalyzed direct o-C-H iodination of benzaldehydes was successfully developed with the assistance of com. available 2,5-bis(trifluoromethyl)aniline as the optimal monodentate transient directing group (MonoTDG). Moderate to excellent yields and good selectivity were achieved for a broad substrate scope under mild conditions. More importantly, the synthetic application was demonstrated by a concise two-step total synthesis of the natural product hernandial, which was accomplished by merging this new MonoTDG-assisted C-H iodination and subsequent copper-catalyzed cross-coupling.
