摘要:
Compounds of the formula (I) give a cooling sensation to the mouth and skin. In Formula I, m is 0 or 1, Y and Z are selected independently from the group consisting of H, OH, C1-C4 straight or branched alkyl, or, a C1-C4 straight or branched alkoxy, X is (CH2)n-R, where n is 0 or 1 and R is a group with non-bonding electrons, with the provisos that: (a) when Y and Z are H, X is not F, OH, MeO or NO2 in the 4-position and is not OH in the 2 or 6-position; (b) when Y or Z is H then X, Y and Z are such that (i) the groups in the 3- and 4-positions are not both OMe, (ii) the groups in the 4- and 5-positions are not both OMe, (iii) the groups in 3- and 5-positions are not OMe if the group in the 4-position is OH, and (iv) the groups in the 3- and 5-positions are not OH if the group in the 4-position is methyl. The compounds give a cooling sensation up to ten times more powerful than the best current commercial materials.
摘要:
The present invention relates to compounds of the general formula (I) and salts and physiologically functional derivatives thereof, wherein A is a non-aromatic ring system containing 4 to 8 carbon atoms, wherein the ring system comprises at least one double bond and wherein one or more of the carbon atoms in the ring can be replaced by a group X, wherein X is selected from the group consisting of S, O, N, NR4, SO, CO or SO2; D is O, S, SO2, NR4 or CH2; Z1 and Z2 are independent from each other O, S, or NR5 ; R2 is H, OR6, or NHR7; E is an alkyl or cycloalkyl group or a monocyclic or polycyclic substituted or unsubstituted ring system which may contain one or more groups X and which contains at least one aromatic ring; Y is hydrogen, halogen, haloalkyl, haloalkyloxy, alkyl, cycloalkyl, a monocyclic or polycyclic substituted or unsubstituted ring system for the use as a medicament.
摘要:

摘要:
Neue Stereoisomere von N-(R)-(1-Aryl-ethyl)-1-alkyl-2,2-dichlor-cyclopropancarbonsäureamiden der Formel (Ia) und (Ib) und deren Gemische, in welchen R¹, R² und X die in der Beschreibung gegebenen Bedeutungen haben, deren neue Zwischenprodukte - die entsprechenden Carbonsäureester, Carbonsäuren und Carbonsäurechloride - und die Verwendung der Stereoisomeren bzw. der Gemische der Verbindungen der Formeln (Ia) und (Ib) zur Bekämpfung von Schädlingen. Die neuen Verbindungen werden durch die Formeln (Ia) und (Ib) allgemein definiert und können nach Analogieverfahren z.B. aus geeigneten Carbonsäurechloriden mit geeigneten Aminen hergestellt werden und gegebenenfalls die Stereoisomerengemische getrennt werden.
