一般描述
1-Acetoxy-1,3-butadiene (1-ABD) can be generated by potassium or sodium acetate catalyzed reaction between crotonaldehyde and acetic anhydride. The product is a mixture of cis and trans forms, that has been confirmed by its physical properties and IR spectra. It is reported to be formed as a major product during the acetoxylation of 1,3-butadiene (BD) in gas-phase in the presence of Pd-KOAc (palladium-potassium acetate) catalyst. 1-ABD participates as 2Π or 4Π diene in cycloaddition reactions. Enantioselective Diels Alder reaction of 2-methoxy-5-methyl-1,4-benzoquinone with 1-ABD in the presence of molecular sieves (mesh size:4Å) has been reported.
应用
1-Acetoxy-1,3-butadiene was used as diene in the following reactions:
It was used for the reaction with dienophiles such as maleimides, a juglone, a butyne-1,4-dione and methyl 2-(4-methylphenyl)-2H-azirine-3-carboxylate and during visible light photocatalysis. It was also used as reactant during intermolecular oxa-Pictet-Spengler cyclization.
- Diels-Alder reaction with ortho-carbazolequinones to yield benzocarbazolequinone.
- Diels-Alder reaction with diethyl ketovinylphosphonate, with and without Lewis acid assistance.
- Diels-Alder reaction with methyl acrylate to yield racemic forms of 2-hydroxy-3-cyclohexenecarboxylic acid.
It was used for the reaction with dienophiles such as maleimides, a juglone, a butyne-1,4-dione and methyl 2-(4-methylphenyl)-2H-azirine-3-carboxylate and during visible light photocatalysis. It was also used as reactant during intermolecular oxa-Pictet-Spengler cyclization.

Ruthenium(II) polypyridyl complexes promote the efficient radical cation Diels-Alder cycloaddition of electron-rich dienophiles upon irradiation with visible light. These reactions enable facile [4 + 2] cycloadditions that would be electronically mismatched under thermal conditions. Key to the success of this
商品
The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. It is also referred to as a cycloaddition.
