摘要:The present invention relates to a process for the preparation of enantiomerically enriched cyclobutylamines of formula (I) from α-tertiary cyclobutanones and reacting said enantiomerically enriched cyclobutylamines to enantiomerically enriched cyclobutylamides. Such compounds are useful intermediates in the synthesis of microbiocidal thiazole compounds.

权利人:INOLEX INVESTMENT CORP
摘要:A process is incorporated herein for the synthesis of bio-1,2-alkanediols, comprising: providing a bio-alkene having a carbon chain of about 5 to about 20 carbon atoms and a bio-1-alkene regioselectivity of at least about 80%, at least about 92% and/or at least about 95%; and converting the bio-alkene to a bio-1,2-alkanediol having a carbon chain length of about 5 to about 20 carbon atoms. Methods for treating catalysts which may be incorporated in the process for the synthesis of bio-1,2-alkanediols are also included herein. Such bio-1,2-alkanediols are used in compositions and products alone as antimicrobial materials, or with existing bio-compounds and/or antimicrobials, preservatives, alternative preservation systems and/or hurdle technology components. The bio-1,2-alkanediols incorporate a natural and bio-based pathway for antimicrobial effects in various compositions such as cosmetic, pharmaceutical, industrial and household products.

标题 :Formulations containing insect repellent compounds
发明人：SCIALDONE MARK A
权利人:DU PONT
摘要:Dihydronepetalactone, a minor natural constituent of the essential oil of catmints ( Nepeta spp.) such as Nepeta cataria , has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.

摘要:The present invention relates to pseudoceramide derivatives represented by formula(I) or (II):wherein, each of R1 and R2 represents linear or branched alkyl group or alkenyl group having 6~22 carbon atoms; each of R3 and R4 represents hydrogen, methyl, ethyl, propyl, or linear or branched C2~C6 alkyl group having one or more hydroxyl group(s), or monosaccharide, a process for preparing the same, and dermatologic external preparations containing the same. When the pseudoceramide derivatives according to the present invention are applied in an dermatologic external preparations the moisture-retaining property and resilience of skin and hair is enhanced such so that the derivatives are useful in protection of skin-aging. In addition, the derivatives are useful for inducing the formation of lipid layer on damaged skin and for preventing the inhibition of lipid synthesis.
