    Abstract: PROBLEM TO BE SOLVED: To provide a method for production an 2-alkyl-2-cyclopentenone in high productivity and yield in a few solvent by bringing an alkylidnecyclopentanone into contact with a hydrogen halide under a specific temperature condition by using an alcohol as a solvent. SOLUTION: (A) An 2-alkylidenecyclopentanone of formula I (R is a 2-8C alkyl) is brought into contact with (C) a hydrogen halide at 150-190 deg.C in (B) an alcoholic solvent to provide (D) an 2-alkyl-2-cyclopentenone of formula II. Preferably, the components A and B are charged at first and the component C is added thereto simultaneously or within 30 min to provide the component D. For example, 2-penthylidenecyclo-pentanone and hydrogen chloride are dissolved in 1-butanol and the solution is heated at 160 deg.C and stirred at the same temperature for 2 hr under heating and after finishing the reaction, the solvent is distilled away and the residue is distilled under reduced pressure to 2-pentyl-2- cyclopentenone. Thereby, the objective compound is industrially advantageously obtained in high yield.

    Abstract: PROBLEM TO BE SOLVED: To obtain cyclohexylmethanol which is a new compound having voluminous floral perfume and useful as an aromatizing component for toiletry goods such as soap, shampoo, rinse, detergent and cosmetic. SOLUTION: The objective compound is expressed by formula I (R1 is H or methyl; and the bond of formula II is single or double bond and either one of two bonds of formula II is double bond; the wavy line shows a cis isomer or trans isomer), e.g. the compound of formula III. The compound of formula I can be produced e.g. by reacting 4-hydroxymethylcyclohexane carbaldehyde with acetone or methyl ethyl ketone in the presence of a basic catalyst preferably at 0-50 deg.C to obtain an α,β-unsaturated ketone of formula IV, reducing exclusively the carbonyl group of the ketone in the presence of a cerium salt at 0-60 deg.C preferably using a reducing agent and dehydrating the obtained compound of formula V preferably in the presence of an inorganic acid or organic acid in a solvent such as toluene at 50-150 deg.C.

    Abstract: PROBLEM TO BE SOLVED: To economically obtain a dihydropyran derivative in high productivity and yield by reacting aldehydes with a diene compound in the presence of a Lewis acid catalyst and a specific cocatalyst. SOLUTION: An aldehyde of the formula, R -CHO (R is H, 1-12C alkyl, 6-12C aryl or the like which may be substituted with an alkyl) is reacted with a diene compound of formula I (R and R are each H, a 1-6C alkyl or alkenyl) in the presence of a Lewis acid catalyst and a cocatalyst without any solvent or in a solvent at -30 to 100 deg.C to provide the objective 5,6-dihydro-2H-pyran derivative of formula II. A compound (excluding a nitro compound) having weaker coordination force to Lewis acid than the aldehyde and having action dissolving the Lewis acid into a solvent by coordinating to Lewis acid is used as the cocatalyst and, e.g. one or two or more kinds of compounds selected from aliphatic or aromatic esters, chloroacetic esters, ethers, ketones and carbonates are used in an amount of 0.1-10 mol based on 1 mol Lewis acid.

    Abstract: PURPOSE:To obtain 2-methyl-1-undecanal useful as perfume from an inexpensively obtainable raw material economically and extremely advantageously. CONSTITUTION:A mixture of (A) 1-undecanol and (B) 2-methyl-1-undecanal is dehydrogenated and the unreacted raw material A is separated from the reaction mixture to give a mixture of (C) 1-undecanal, (D) 2-methyl-1-decanal and the unreacted raw material B. The unreacted raw material A is preferably used as the above-mentioned raw material. Then the mixture of the components B to D is allowed to react with formaldehyde or a formaldehyde-forming substance in the presence of an amine to give a mixture of (E) 2-methylene- undecanal, an intermediate D and the unreacted raw material B. The mixture is hydrogenated to give a mixture of (F) 2-methyl-1-undecanal, the intermediate D and the unreacted raw material B. Further, the unreacted raw material B in the mixture is converted into a boric ester to separate the objective compound F.
