| titleOfInvention | Production of (s)-gamma-hydroxymethyl alpha,beta-butenolide |
| abstract | PURPOSE: To obtain the title compound useful as a synthetic raw material for drugs such as prostaglandin and anti-leukemic lignan inexpensively and in high yield by oxidizing levoglucosenone as a starting raw material with a peracid in an organic solvent. n CONSTITUTION: Levoglucosenone as a raw material is oxidized with a peracid in an organic solvent at room temperature while stirring to give the objective compound. Peracetic acid, m-chloroperbenzoic acid, magnesium monoperoxyphthalate.6 hydrate, etc., may be cited as the peracid. The amount of the peracid used is 1.0-3.0mols based on 1mol levoglucosenone. Acetic acid, methylene chloride, methanol, etc., are properly used as the organic solvent. Levoglucosenone can be inexpensively and readily obtained by thermally decomposing cellulose. n COPYRIGHT: (C)1991,JPO&Japio |
