摘要:
Compounds, compositions, and methods for controlling an arthropod pest population that employ an eremophilane sesquiterpene parent structure are presented. The compounds have minimal adverse or toxic effects on humans, non-human animals, and the natural environment. The compounds may be isolated from natural sources, semi-synthesized from naturally occurring compounds, or completely synthesized. The compounds may be applied directly to a pest, or the locus of a pest, and function as topical or ingestible toxins. Eremophilane sesquiterpenes 13-hydroxy-valencene, valencene-11,12-epoxide, valencene-13-aldehyde, and nootkatone-1,10-11,12-diepoxide are exemplary compounds.

Verbindungen der Formel und die punktierten Linien fakultative zusätzliche C-C-Bindungen mit E- oder Z-Konfiguration bedeuten und die übrigen Symbole die in Anspruch 1 angegebene Bedeutung besitzen, sowie pharmazeutisch verwendbare Salze davon haben mucosa-protektive und magensäuresekretionshemmende Eigenschaften und können zur Behandlung von Ulcus ventriculi und/oder duodeni verwendet werden. Sie sind neu, mit Ausnahme von 10-Hydroxy-3,7,11-trimethyl-2,6,11-dodecatriensäure und 3,7,11-Trimethyl-2,6,11-dodecatrien-1,10-diol. Sie können zu galenischen Darreichungsformen verarbeitet und nach verschiedenen Verfahren hergestellt werden.

摘要:
New plant growth regulators, including compounds and compositions, and methods of use including for promoting root growth. The compounds are carotenoid oxidation products, and a preferred example is 3-OH-β-apo-13-Carotenone. A method comprising promoting the growth of at least one plant with use of an effective amount of at least one composition comprising an effective amount of at least one compound which is represented by A-B-C, wherein B is a bivalent polyene moiety, A is a monovalent moiety linked to B by a six-membered carbon ring, wherein the ring has at least one substituent linked to the ring by an oxygen atom, and C is a monovalent moiety linked to B by a carbonyl group. Synergistic effects can be used with combinations of compounds.
摘要:
A two-step aldol condensation process is disclosed. α-Campholenic aldehyde (ACA) and methyl ethyl ketone (MEK) react in the presence of a base under conditions effective to produce a mixture comprising a high yield of ketol condensation products. Dehydration of the ketols in the presence of an organic sulfonic acid provides unsaturated ketones that are valuable intermediates for fragrance components for synthetic sandalwood products. Compared with the usual one-step, base-catalyzed approach, the two-step process increases the yield of all condensation products and maximizes production of the most valuable ketone isomers.
摘要:
The present invention relates to analogues of vitamin D, which lack the combined presence of the trans-fused six-membered C-ring and of five-membered D-ring, but still possess a central part consisting of a substituted chain of five atoms, atoms which correspond to positions 8, 14, 13, 17 and 20 of vitamin D, and at the ends of which are connected, at position 20 a structural moiety representing part of the side-chain of vitamin D or of an analogue of vitamin D, and at position 8 the Δ(5,7)-diene moiety connected to the A-ring of the active 1-alpha-hydroxy metabolite or of an established vitamin D analogue, to their preparation process, to pharmaceutical preparations comprising these compounds and to their use in medicine.
