General description

Salicylaldehyde is the main odor constituent of buckwheat flour. It is also found in anise and vanilla extracts.

Application

  • Facile synthesis of iminated lignin for enhanced free radical and lead ion scavenging capabilities.: This study presents a novel method for synthesizing iminated lignin using salicylaldehyde. The modified lignin demonstrates significantly improved free radical and lead ion scavenging abilities, highlighting its potential application in environmental remediation and biochemical processes (Xia et al., 2024).

The catalytic enantioselective three-component Petasis reaction among salicylaldehydes, amines, and organoboronic acids with a newly designed thiourea-binol catalyst is presented. A broad range of alkylaminophenols can be obtained in good yield (up to 92%) and good to high enantioselectivity (up

The gold(I)/chiral Brønsted acid relay catalysis enabled a highly stereoselective three-component reaction of salicylaldehydes, anilines, and alkynols to give aromatic spiroacetals in high yields and stereoselectivities.

We synthesized two constitutionally isomeric bis(iminomethyl)-2,6-dihydroxynaphthalenes, namely, α,α-diimines 1 and β,β-diimines 2, which can be formally represented as fused salicylaldimines with resonance-assisted hydrogen-bonding sites. Spectroscopic data show that the OH/OH, NH/OH, and NH/NH forms of 1 were in equilibrium in
