20090124826 | Optically Active 3-Methylcyclopentadecanone And Method For Producing Intermediate Thereof - Disclosed is a method for producing an optically active 3-methylcyclopentadecan-1-one which is characterized in that 2-cyclopentadecen-1-one is subjected to a 1,4-conjugate addition reaction of a methyl group by using a methylated organic metal in the presence of a copper catalyst, an enol anion scavenger and a specific optically active phosphoramidite for obtaining an optically active 3-methyl-1-cyclopentadecene derivative, and then the thus-obtained 3-methyl-1-cyclopentadecene derivative is subjected to a solvolysis. | 05-14-2009 |
20090143485 | OPTICALLY ACTIVE MUSCONE COMPOSITION AND FRAGRANCES OR COSMETICS CONTAINING THE SAME - (Problem) The object of the invention relates to a development of a new musk-feeling fragrance material which is a highly scenting musk-feeling fragrance, and is to provide a fragrance composition which, when added to fragrances or cosmetics, can improve the fixative property and express a high performance and excellent musky aromatic quality. | 06-04-2009 |
20090270516 | Process for Producing Optically Active Theaspirane - A simplified production method of stereoisomer of theaspiran having high optical purity has been desired. An alcohol compound having a specific skeleton is enantioselectively esterified with an enzyme, or an ester compound having a specific skeleton is enantioselectively hydrolyzed with an enzyme. The resultant optically active ester or optically active alcohol is used. Thus, optically active theaspiran having a desired configuration and having a high optical purity is obtained in a satisfactory yield. | 10-29-2009 |
20100305216 | OPTICALLY ACTIVE MUSCONE COMPOSITION AND FRAGRANCES OR COSMETICS CONTAINING THE SAME - (Problem) The object of the invention relates to a development of a new musk-feeling fragrance material which is a highly scenting musk-feeling fragrance, and is to provide a fragrance composition which, when added to fragrances or cosmetics, can improve the fixative property and express a high performance and excellent musky aromatic quality. | 12-02-2010 |

20110313201 | OPTICALLY ACTIVE MUSCONE COMPOSITION AND FRAGRANCES OR COSMETICS CONTAINING THE SAME - (Problem) The object of the invention relates to a development of a new musk-feeling fragrance material which is a highly scenting musk-feeling fragrance, and is to provide a fragrance composition which, when added to fragrances or cosmetics, can improve the fixative property and express a high performance and excellent musky aromatic quality. | 12-22-2011 |
20150275131 | FRAGRANCE COMPOSITION - A fragrance composition contains (3S)-(6E)-2,3-dihydrofarnesal. A chemical purity of the (3S)-(6E)-2,3-dihydrofarnesal is 90 mass % or more and an optical purity of the (3S)-(6E)-2,3-dihydrofarnesal is 50% e.e. or more. A fragrance or cosmetic contains the fragrance composition. An odor is improved by using the fragrance composition containing (3S)-(6E)-2,3-dihydrofarnesal having a chemical purity of 90 mass % or more and an optical purity of 50% e.e. or more. | 10-01-2015 |
20150329452 | METHOD FOR PRODUCING OPTICALLY ACTIVE ISOPULEGOL AND OPTICALLY ACTIVE MENTHOL - A method for producing an optically active isopulegol includes asymmetrically isomerizing a specific compound in the presence of a ruthenium catalyst and a base, thereby giving an optically active citronellal, and selectively cyclizing the optically active citronellal in the presence of an aluminum catalyst. The aluminum catalyst is obtained by reacting a specific hydroxy compound and at least one aluminum compound selected from a specific alkylaluminum compound, a specific hydride aluminum compound, a specific linear aluminoxane and a specific cyclic aluminoxane. | 11-19-2015 |
