A microfluidic photoreactor enables 2-methylbenzophenone light-driven reactions with superior performance

Light-driven reactions of 2-methylbenzophenones (2-MBPs) occur with improved yields (up to >98%) and reaction rates (up to 0.240 mmol h-1) by using a tailored microfluidic photoreactor (MFP). For the first time, coumarins were converted into 4-

Combined Photoredox/Enzymatic C?H Benzylic Hydroxylations

Chemical transformations that install heteroatoms into C?H bonds are of significant interest because they streamline the construction of value-added small molecules. Direct C?H oxyfunctionalization, or the one step conversion of a C?H bond to a C?O bond, could be a highly enabling transformation due to the prevalence of the resulting enantioenriched alcohols in pharmaceuticals and natural products,. Here we report a single-flask photoredox/enzymatic process for direct C?H hydroxylation that proceeds with broad reactivity, chemoselectivity and enantioselectivity. This unified strategy advances general photoredox and enzymatic catalysis synergy and enables chemoenzymatic processes for powerful and selective oxidative transformations.

Synthesis of Tofisopam by Way of Photoinduced CO2 Fixation

Herein reported is a unique synthetic route of Tofisopam, an anxiolytic drug containing a 2,3-benzodiazepine core structure. 3,4-Dimethoxypropylbenzene and 3,4-dimethoxybenzoic acid, which are both of plant origin, and CO2 constitute its carbon skeleton. These three renewable substances are united by two C?C bond forming reactions, i.e., a Friedel–Crafts acylation reaction and a photoinduced carboxylation reaction to construct the major carbon framework. Finally, a methyl group is introduced by a Kumada-type cross-coupling reaction to furnish Tofisopam. Various analogs of Tofisopam are readily synthesized by introducing other substituents than a methyl group at the last C?C bond forming step.

Light-Driven Carboxylation of o-Alkylphenyl Ketones with CO2

o-Alkylphenyl ketones undergo a C-C bond forming carboxylation reaction with CO2 simply upon irradiation with UV light or even solar light. The reaction presents a clean process exploiting light energy as the driving force for carboxylation of organic molecules with CO2.

A novel tandem [2 + 2] cycloaddition-Dieckmann condensation with ynolate anions. Efficient synthesis of substituted cycloalkenones and naphthalenes via formal [n + 1] cycloaddition

A novel tandem [2 + 2] cycloaddition-Dieckmann condensation via ynolate anions is described. Ynolate anions are useful for the formation of reactive β-lactone enolates via a pathway not involving the enolization of the corresponding β-lactones. The [2 + 2] cycloaddition of ynolate anions with δ- or σ-keto esters, followed by Dieckmann condensation, gives bicyclic β-lactones, which are easily decarboxylated to produce synthetically useful 2,3-disubstituted cyclopentenones and cyclohexenones in one pot. This tandem reaction was applied to a novel, one-pot synthesis of highly substituted naphthalenes.

Reactions of carbonyl compounds in basic solutions. Part 21. The mechanisms of the alkaline hydrolysis of substituted methyl 2-(2-oxopropyl)- and 2-(2-oxo-2-phenylethyl)-benzoates and 2-(2-acetylphenyl)- and 2-(2-benzoylphenyl)-acetates

Rate coefficients have been measured for the alkaline hydrolysis of methyl 2-[2-oxo-2-(3- or 4-substituted phenyl)ethyl]benzoates, 2-[2-(3- or 4-substituted benzoyl)phenyl]acetates,2-(2-oxopropyl) and 2-(1,1-dimethyl-2- oxopropyl)benzoates, 2-(2-acetylphenyl)acetate and 2-(2-acetylphenyl)-2,2- dimethylacetates in 70% (v/v) dioxane-water at 30.0 °C. Those for the six parent esters were also measured at 45.0 and 60.0 °C and the enthalpies and entropies of activation have been evaluated. The relative rates of hydrolysis, activation parameters and substituent effects have been used to demonstrate neighbouring participation by the keto-carbonyl groups in the alkaline hydrolysis of the esters under study. For comparable systems, participation by six-membered ring intermediates appears somewhat less advantageous than five-membered.

Synthesis and X-Ray Analysis of 2,3,5,6,11-Pentaoxabicycloundecanes

The reactions of bicyclic ozonides and aldehyde- or ketone-derived peroxides, performed or generated in situ, in the presence of chlorosulphonic acid afford the corresponding 2,3,5,6,11-pentaoxabicycloundecanes.In addition, 1,2,4,5-tetraoxans are often isolated from the product mixture.Mechanisms are proposed to account for the observed peroxidic products.An X-ray analysis of the crystalline product (4b) confirms the general structure and reveals that it is solely the exo-isomer.

Synthesis, X-ray Analysis, and Acidolysis of exo- and endo-1-Methylindene Ozonides

Ozonolyses of 2,3-disubstituted 1-methylindenes gave mixtures of the corresponding exo and endo ozonides.The structures of endo-1-methyl-3-phenylindene ozonide (3a) and exo-1-methyl-2,3-diphenylindene ozonide (2b) were determined by the X-ray analysis.Acidolysis of exo- and endo-1-methylindene ozonides 2a-d and 3a-d under several conditions revealed some characteristic features. (a) Antimony pentachloride or chlorosulfonic acid catalyzed the interconversion of the exo-endo ozonide isomers, the ratio in equilibrium being ca. 7:3 for all the pairs. (b) In the reaction of 3-methyl-substituted indene ozonides 2c,d and 3c,d in acetic-d3 acid-d a rapid hydrogen-deuterium exchange on the bridgehead methyl was observed. (c) In methylene chloride or acetic acid the ozonides decomposed very slowly, yielding the mixtures of rearranged products 4 and 5, carboxylic acid 6, and diketone 7; both the rate of decomposition and the product distribution being a marked function of the structure of the ozonides. (d) Methanol accelerated the decomposition of ozonides, the disappearance following pseudo-first-order kinetics.The rate decreased in the order 3a > 2a > 2b > 2c ca. 3c > 3b.This order was significantly different from the order observed in the reaction in acetic acid: 3b > 3c > 2b > 2c > 3a > 2a. (e) Reduction by AlHCl2 gave a mixture of 3,4-dihydro-1H-2-benzopyrans 19 - 22, the composition being significantly varied depending on the stereochemistry of the ozonides. (f) Treatment of 2a or 3a with bis(α-hydroxy-4-methylbenzyl)peroxide (31) gave two stereoisomeric peroxides 32a and 33a in roughly equal amounts.In contrast, the reaction of an exo ozonide 2d with a mixture of p-tolualdehyde and 30percent H2O2 (an equivalent of 31) afforded exclusively the corresponding exo peroxide 32d, while the endo isomer 3d gave predominantly the endo peroxide 33d.
