| titleOfInvention | Process for producing (3S, 4R) -3-hydroxy-4-hydroxymethyl-4-butanolide |
| abstract | (57) [Summary] (Modified) [Structure] By hydrating the carbon-carbon double bond of levoglucosenone [1] and introducing a hydroxyl group of α-configuration at the 4-position with a methylene group at the 4-position, the formula [2] And a step of converting the compound of the formula [2] into a five-membered lactone by Bayer-Villiger oxidation, (3S, 4R) -3-hydroxy-4- A method for producing hydroxymethyl-4-butanolide [3]. [Effect] (3S, 4R) -3-Hydroxy-4-, which is one of hydroxy lactones which has been difficult to obtain conventionally It has become possible to selectively obtain hydroxymethyl-4-butanolide from levoglucosenone as a starting material by a simple operation in a short process and in a high yield. Thereby, it can be easily supplied as a raw material for synthesizing various useful compounds. |
