摘要： NEW MATERIAL:A liquid crystal compound bearing an optically active gamma-lactone ring [R is formulas II, III, or IV (n, e are 0, 1; R is 1-15C alkyl); R is -(CO)mR (R is 1-15C alkyl), * means asymmetric carbon atom). EXAMPLE:The compound of formula V. USE:A liquid crystal compound for display elements or electrooptical elements. The asymmetric part is directly connected to the 5-membered ring to restrict the free rotation so that the compound is chemically stabilized with stabilized ferroelectricity. PREPARATION:The reaction of an optically active glycidyl ether of formula VI with a beta-ketoester derivative of formula VII or and a malonic acid ester of formula VIII (R is lower alkyl) is conducted in an organic solvent in the presence of an base to give a liquid crystal compound having an optically active gamma-lactone ring of formula I.

摘要： PURPOSE:To obtain a granular immobilized substance excellent in mechanical strength while maintaining the activity of a microorganism good by preparing an immobilized substance of a microorganism-calcium alginate and polymerizing the resultant substance in a polyacrylamide polymerization system. CONSTITUTION:A mixed solution of a microorganism and sodium alginate is initially dripped into an aqueous solution of calcium chloride to provide a granular immobilized substance of the microorganism-calcium alginate, which is then dipped in an aqueous solution for polymerizing acrylamide monomer. A polymerization initiator is subsequently added to carry out polymerization. For example, a solution prepared by blending a crosslinking agent, such as N,N'-methylenebisacrylamide, and a polymerization accelerator, such as beta- dimethylaminopropionitrile, is used as the solution for polymerizing the acrylamide monomer.

USE:A synthetic intermediate for pharmaceuticals, agricultural chemicals, other physiologically active substances, ferroelectric liquid crystal material, etc. Since the compound has especially high optical purity, it is excellent as a production raw material for high-purity optically active substance. PREPARATION:An optically active epichlorohydrin of formula II is made to react with a hydrogen nucleophilic compound or a carbon nucleophilic compound and the obtained compound of formula III is made to react with thiophenol to obtain a sulfide derivative of formula IV. The reaction is carried out in a solvent such as THF at -78--30 deg.C. The produced derivative is oxidized with an oxidation agent (e.g. peracid) to obtain the objective compound of formula I (R is H).
