Patent number: 5412111Abstract: Providing a method of preparing (3R,4R)-3-hydroxy-4-hydroxymethyl-4-butanolide conveniently and selectively from a widely available raw material in a high yield. A carbonyl group of the 2-position of levoglucosenone is reduced to obtain a hydroxyl group of a .beta.-configuration. Then, an iodo-group of an .alpha.-configuration and an acyloxy ion of a .beta.-configuration are introduced regioselectively and stereoselectively to the double bond at the 4-position and the 3-position of the above-mentioned levoglucosenone, respectively, keeping a trans stereochemical relationship. An alkoxide is then formed, by hydrolysis and an oxirane ring of a .beta.-configuration is formed by removing an iodo-group by intramolecular nucleophilic displacement reaction of the alkoxide.Type: GrantFiled: July 23, 1993Date of Patent: May 2, 1995Assignee: Japan Tobacco IncorporatedInventors: Katsuya Matsumoto, Takashi Ebata, Koshi Koseki, Koji Okano, Hiroshi Kawakami, Hajime Matsushita
