摘要： In the method of the present invention for manufacturing 3-DPA-lactone, a protective group is introduced in the first step into the hydroxyl group at 4-position of .gamma.-ribonolactone by an ordinary method. Then, an acid anhydride or an acid chloride is added in the presence of a tertiary amine compound so as to conduct a .beta.-elimination of the hydroxyl group at the 3-position. As a result, a double bond is formed between the 2- and 3-positions and, at the same time, the hydroxyl group at the 2-position is acylated. The double bond between the 2- and 3-positions is reduced in the next step by means of a catalytic hydrogenation. Finally, the protective group of the hydroxyl group is eliminated by an ordinary method. The particular method permits using readily available raw materials, decreasing the number of manufacturing steps, and easily and selectively synthesizing the desired 3-DPA-lactone, which is hardly obtained from nature in a large amount, in high yield, compared with the conventional method.

摘要： 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. After the hydroxyl group of the 2-position is oxidized to convert to a carbonyl group, the oxirane ring is reductively and selectively cleaved, thereby obtaining a chemical compound having no substituent at the 3-position and a hydroxyl group of a .beta.-configuration at the 4-position. Finally a lactone of 5-membered-ring is prepared by subjecting the above-obtained compound to Baeyer-Villigar oxidation.

摘要： After the lactone portion of trans-whiskey lactone is hydrolyzed with potassium hydroxide, this portion is reacted with isopropyl bromide and mixed with an alkyl group, thereby obtaining isopropyl (3S,4S)-4-hydroxy-3-methyloctanoate. Then, the isopropyl (3S,4S)-4-hydroxy-3-methyloctanoate is reacted with diethyl azodicarboxylate in the presence of triphenylphosphine and azodicarboxylate, thereby obtaining isopropyl (3S,4S)-4-(3',5'-dinitrobenzoyloxy)-3-methyloctanoate. The isopropyl (3S,4S)-4-(3',5'-dinitrobenzoyloxy)-3-methyloctanoate is hydrolyzed in 2% potassium hydroxide, and as a result, cis-whiskey lactone (A) represented by the following general formula is obtained. According to this method, cis-whiskey lactone, one of the perfume components of whiskey and wine, can be produced selectively and easily. ##STR1##

摘要： An alkynyl group having a triple bond at the carbon atom at the 1-position is introduced to a carbon atom at the 1-position of 2,3-O-isopropylidene-D-ribofuranose. The diol part is then cleaved to obtain a lactol compound. This lactol compound is oxidized to obtain a lactone compound. The ketal part of the lactone compound is hydrolyzed and the compound is further subjected to a reduction reaction. The hydroxyl groups at the 2- and 3-positions are then eliminated, and the double bond between the 2- and 3-positions of the resultant compound is reduced to obtain a 4-substituted-.gamma.-lactone.
