Hisashi Yamamoto and coworkers have developed a practical Diels-Alder catalyst for aldehyde dienophiles.
cis-3-Hexenal, also known as (Z)-3-hexenal and leaf aldehyde, is colorless liquid and an aroma compound with an intense grassy-green odor of freshly cut green grass and leaves.
The substances are prepared via a Knoevenagel condensation of a thiohydantoin–phenylalanine imine with different aldehydes, which yields a mixture of E and Z isomers.
The anthraquinone aldehyde nordamnacanthal (1,3-dihydroxy-anthraquinone-2-al) present in G. aparine has an antifeedant activity against Spodoptera litura, the Oriental leafworm moth, a species which is considered an agricultural pest.
Grundmann aldehyde synthesis, chemical reaction that produces an aldehyde from an acyl halide
Hantzsch pyridine synthesis, multi-component organic reaction between an aldehyde a β-keto ester and a nitrogen donor
The Parikh–Doering oxidation is an oxidation reaction that transforms primary and secondary alcohols into aldehydes and ketones, respectively.
The Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol is oxidized to an aldehyde or ketone using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.
