Abstract: A vehicle upper structure reduces noise in a cabin by preventing vibration of a roof panel while avoiding an increase in manufacturing cost and an increase in vehicle weight. A vehicle includes a roof panel, a front header, a ceiling, and a vibration damping member. The front header extends in a vehicle width direction on an inner side of the cabin from the roof panel. The ceiling covers the roof panel from the inner side of the cabin. The vibration damping member is fixed to an upper surface of the ceiling. The vibration damping member is arranged between a sun visor fixed portion and a gusset fixed portion in the vehicle width direction and near the front header. The vibration damping member has at least two resonance frequencies and is configured such that one resonance frequency thereof is substantially the same as a resonance frequency of the ceiling.

Abstract: The invention provides processes for producing efficiently optically active 2-halogenocarboxylic acids useful in the preparation of drugs or the like and salts thereof with amines. Specifically, an optically active 2-halogenocarboxylic acid is produced by halogenating an optically active amino acid in water in the presence of a hydrophobic organic solvent and nitrous acid with the configuration retained and with the racemization inhibited through the removal of 2-hydroxy-bromocarboxylic acid formed as a by-product; the obtained optically active 2-halogenocarboxylic acid is transferred to an aqueous phase by converting it into a salt thereof with a base, followed by the removal of the organic phase; and the optically active 2-halogenocarboxylic acid is transferred again to an organic solvent phase, followed by the removal of the aqueous phase, whereby an optically active 2-halogenocarboxylic acid is obtained through the removal of a halogen component.

Thus, an optically active 2-chlorocarboxylic acid chloride (5) is induced. The compound (5) is hydrolyzed to induce an optically active 2-chlorocarboxylic acid (2). The compound (2) is reacted with a thioacetic acid salt to incorporate an acetylthio group thereinto and simultaneously invert the configuration in the 2-position to thereby produce an optically active 2-acetylthiocarboxylic acid (3).

Abstract: The present invention relates to a process for efficiently producing an optically active 2-bromocarboylic acid and an optically active 2-sulfonyloxycarboxylic acid, which are important in the production of medicinal compounds and so forth. An optically active 2-sulfonyloxycarboxylic acid ester is subjected to deprotection under acid conditions to obtain an optically active 2-sulfonyloxycarboxylic acid. A metal bromide is caused to act on the acid to brominate it with configuration inversion at position 2 to thereby produce an optically active 2-bromocarboxylic acid. The resultant optically active 2-bromocarboxylic acid is isolated/purified by subjecting it to a step in which the acid is crystallized and separated as a salt with a base. Thus, an optically active 2-bromocarboxylic acid having a high chemical purity and high optical purity can be produced.
