Description and Uses

1-Acetoxy-1,3-butadiene was used as diene in the following reactions:

• 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.
