Paragraph 0189-0192, (2021/07/17)
The invention relates to an allyl acrylate compound for preparing spiro lactone, the spiro lactone and a preparation method of the spiro lactone, and belongs to the technical field of organic synthesis. The allyl acrylate compound for preparing spirolactone has a structural formula shown as a formula II. A carbon-carbon double bond in allyl ester is located in a ring, the carbon-carbon double bond is separated from ester by a carbon atom, and a carbon-carbon double bond in acrylic acid is adjacent to a carbonyl group of an ester group, so that the compound can be activated under a photocatalysis effect and is further converted into spiro lactone. The invention also provides the preparation method of the spiro-lactone. The spiro-lactone is obtained by carrying out photocatalytic reaction on the allyl acrylate compound. The method does not need to introduce any catalyst and additive, belongs to a green chemical method which is green, high in atom economy, low in toxicity, low in price, mild in reaction condition and environment-friendly, and has important significance on development of green reaction.
