Description

General description

3,4-Dimethoxybenzaldehyde forms 1:1 inclusion complexes with cyclodextrins. It reacts with 3-acetyl-2,5-dimethythiophene to yield chalcone dye, (2E)-3-(3,4-Dimethoxyphenyl)-1-(2,5-dimethylthiophen-3-yl)prop-2-en-1-one.

Application

3,4-Dimethoxybenzaldehyde was used in the preparation of 4-chloromethyl-2-(dimethoxyphenyl)-1,3-dioxolane. It was used in the synthesis of (+)-lithospermic acid, having anti-HIV activity.

Concentrations of a triplet excited state are enhanced in illuminated ice.

Zeyuan Chen et al.

Environmental science. Processes & impacts, 19(1), 12-21 (2017-01-07)

Photochemical reactions influence the fates and lifetimes of organic compounds in snow and ice, both through direct photoreactions and via photoproduced transient species such as hydroxyl radical (˙OH) and, perhaps, triplet excited states of organic compounds (i.e., triplets). While triplets

Synthesis of anti-HIV lithospermic acid by two diverse strategies.

Tirumala G Varadaraju et al.

Organic & biomolecular chemistry, 10(28), 5456-5465 (2012-06-07)

An efficient and convergent route for the synthesis of the natural product (+)-lithospermic acid, which possesses anti-HIV activity, was accomplished. The (±)-trans-dihydrobenzo[b]furan core therein was prepared by two different strategies. The first strategy involved the use of a palladium-catalyzed annulation

Spectral and molecular modeling studies on hydroxybenzaldehydes with native and modified cyclodextrins.

Journal of fluorescence, 24(3), 695-707 (2013-12-07)

The inclusion complexation of 2-hydroxy-3-methoxybenzaldehyde (2HMB), 4-hydroxy-3-methoxybenzaldehyde (4HMB), 3,4-dimethoxybenzaldehyde (DMB) and 4-hydroxy-3,5-dimethoxybenzaldehyde (HDMB) with α-CD, β-CD, HP-α-CD and HP-β-CD were carried out by UV-Visible, steady-state and time-resolved fluorescence and PM3 methods. All the benzaldehydes shows dual fluorescence in aqueous and
