We report the catalytic and transition metal-free reductive deoxygenation of esters to ethers through the use of a hydrosilane and a fluorinated borate BArF salt as a catalyst. Experimental and theoretical studies support the role of noncovalent interactions between the fluorinated catalyst, the hydrosilane and the ester substrate in the reaction mechanism.

The presence of different aldehydes is found to have a significant influence on the catalytic performance when using PN(H)P type ligands for dehydrogenation of alcohols. Accordingly, hybrid multi-dentate ligands were discovered based on an oxygen-transfer alkylation of PNP ligands by aldehydes. The relevant Ru-PNN(PO) system provided the desired unsymmetrical esters in good yields via acceptorless dehydrogenation of alcohols. Hydrogen bonding interactions between the phosphine oxide moieties and alcohol substrates likely assisted the observed high chemoselectivity.

A metal-free organocatalytic system has been developed for highly efficient benzylic C-H oxygenations of cyclic ethers using oxygen as an oxidant. This oxidation reaction utilizes alpha-angelica lactone as a low cost/low molecular weight catalyst. The optimized reaction conditions allow the synthesis of valued isocoumarins and phthalides from readily available precursors in good yields. Mechanistic studies indicate that the reaction pathway likely involves a radical process via a peroxide intermediate.

Kinetics of thermostimulated luminescence (TSL) of poly(diphenylenephthalide) (PDPh) films has been studied using mathematical modelling and DFT approximation. TSL of PDPh-film was considered to be arising from irradiative deactivation of diphenylene (DP) fragment of polymer chain in excited state formed upon recombination of the spatial separated ion-radical pairs generated by photoexcitation. Two parallel monomolecular transformations leading to excited DP have been revealed: the first path is characterized by the activation parameters of the kinetic rate constant k1 which equal to Al ti 105 sec 1 and Eat ti 70 kJ mol(-1). This path may be interpreted in terms of mechanical relaxation theory by segmental polymer mobility as electron transfer (ET) from phthalide (Ph) anion-to DP cation-radical. The second channel is supposed to be consist of two consecutive ET from triarylmethyl anion-radical to phthalide neutral (A2 ti 1 sec 1, Ea2 ti 20 kJ mol(-1)), and then to DP cation-radical (A3 N 104 sec 1, E,3 N 40 kJ mol(-1)) of the polymer chain indicating y- and fl-relaxation, respectively. The revealed mechanistic steps and electron retention efficiency estimated in B97-2/6-311 + G(d,p) approximation for the most probable anion-radicals may point out the key role of domino quantum tunneling in transfer and recombination of charges in PDPh films.

A new, simple, and rapid photochemical reaction of o-phthalaldehyde with C-60 has been disclosed. This reaction afforded exclusively the unanticipated C-60-phthalide derivative 11 in good yield. The formation of this product is consistent with the intervention of a key free-radical intermediate -a benzylic radical- in the course of the reaction. The structure of 11 has been determined by the combined use of experimental and theoretical NMR studies. In the course of this study we further disclosed a new mode of radical reactivity of C-60 with a series of substituted phthalides (2, 15-17) catalyzed by tetrabutylammonium decatungstate.

Considering the anti-infective potential of compounds containing the dibenzothiepine scaffold, we set out to obtain new compounds bearing this structure. The synthesized compounds were characterized by spectral studies and elemental analysis and screened for their microbiostatic/microbicidal and antibiofilm properties against reference and clinical microbial strains. The new compounds exhibited a broad spectrum of antimicrobial activity, which was more intensive for the S-oxidized compounds. Some of the compounds also inhibited the ability of the investigated strains to form biofilms on the inert substratum.

As part of our continuing efforts to discover structurally interesting bioactive phthalide derivatives, 23 of them with a structure incorporating thiophen or halogens were designed and synthesized, 17 of which are previously unreported. In vitro antiplatelet aggregation activity screening showed that 14b could significantly inhibit platelet aggregation induced by arachidonic acid, compared with edaravone (p < 0.01). Meanwhile, oxidative damage models using SH-SY5Y and PC12 cells induced by H2O2 were built to evaluate the antioxidant activity of the phthalide derivatives. In SH-SY5Y cells, compared with aspirin, 1a significantly increased the relative cell survival rate (p < 0.05). Compared with edaravone, 1a (p < 0.01) and 15b (p < 0.05) significantly increased the relative cell survival rate. In PC12 cells, 1a (p < 0.01), 15b (p < 0.01), and 12a (p < 0.05) remarkably increased the cell survival rate compared with edaravone. The present study identified lead structures to develop potential anti-ischemic stroke agents. Category: benzofurans.

A novel asymmetric phase-transfer-catalyzed gamma-alkylation of phthalide 3-carboxylic esters has been developed, giving access to 3,3-disubstituted phthalide derivatives, which present a chiral quaternary gamma-carbon in good to excellent yields and good enantioselectivities (74-88% ee). The enantiomeric purity could be substantially enhanced to 94-95% ee by recrystallization. Both electron-withdrawing and electron-releasing substituents are well tolerated on the phthalide core as well as on the aromatic moiety of the alkylating agent. This methodology, enabling the introduction of an unfunctionalized group at the phthalide gamma-position, fully complements previously reported organocatalytic strategies involving functionalized electrophiles, thus expanding the scope of accessible 3,3-disubstituted products. The high synthetic value of this asymmetric reaction has been proven by the formal synthesis of the naturally occurring alkaloid (+)-(9S,13R)-13-hydroxyisocyclocelabenzine.

Chiral alpha-substituted 1,3-dihydroisobenzofurans are key scaffolds in a number of bioactive natural products and synthetic pharmaceuticals. However, catalytic asymmetric approaches have been rarely developed. Here, a redox deracemization technology is adopted to address the catalytic asymmetric synthesis. A broad range of alpha-aryl substituted 1,3-dihydroisobenzofurans are effectively deracemized in high efficiency with excellent ee. alpha-Alkynyl substituted ethers were also compatible with the deracemization technology.
