The invention also relates to a novel Mg compound of formula (1).
Abstract:
A therapeutic agent for diabetes comprising a compound represented by general formula (I) [wherein X represents (a), (b) or (c)] [wherein R4 and R5, which may be the same or different, represent a hydrogen atom, or an optionally substituted alkyl group having 1 to 5 carbon atoms and R6 represents a hydrogen atom or an amino protective group; R1 represents an optionally substituted alkyl group having 1 to 5 carbon atoms or an optionally substituted alkenyl group having 2 to 6 carbon atoms; R2 represents a hydrogen atom or an optionally substituted alkyl group having 1 to 5 carbon atoms; R2' represents a hydrogen atom; and R3 represents an optionally substituted alkyl group having 1 to 5 carbon atoms], a prodrug compound thereof, a pharmaceutically acceptable salt thereof, a hydrate thereof, or a solvate thereof. The agent has an excellent blood sugar lowering activity in the case of a high blood sugar level, does not influence the blood sugar in the case of a normal blood sugar level, that is, does not cause any severe side effect, such as hypoglycemia, and is useful not only as a therapeutic agent but also as a prophylactic for chronic complications of diabetes.
Abstract:
The present invention relates to the synthesis of intermediate compounds which can be used in the synthesis of mint lactone and related compounds, including 3,6-dimethylhexahydrobenzofuran-2-ones, isomers, and other derivatives.
Abstract:
The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products. Such perfume raw materials and compositions, including the delivery systems, disclosed herein expand the perfume communities' options as such perfume raw materials can provide variations on character and such compositions can provide desired odor profiles.

Abstract:
Killing of bed bugs is accomplished by bringing the bed bugs into contact with a toxic amount of one of the compounds of the structure (I) wherein X is -OH, =O, or -O(O)CR, wherein R is selected from H and a branched or straight chain, saturated or unsaturated hydrocarbyi group with zero to three double bonds and from 1 to 1 1 carbon atoms; R 1 , is H or CH 3 ; R 2 is H or CH 3 ; R 3 is H or a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to three double bonds and from 1 to 11 carbon atoms; and wherein the compounds of structure (I) contain from 6 to 20 total carbon atoms in the compounds.
Abstract:
1-(3/4-isobutyl-1/6-methylcyclohex-3-enyl)methanols and derivatives thereof having appreciable floral and hesperidic odor notes, their use as fragrance ingredient and perfumed products comprising them.
Abstract:
The present invention relates to a process for the carbon-carbon double bond isomerisation of a 2-alkyl-cyclohex-3-enyl alkyl or alkenyl ketone into a mixture comprising the corresponding 2-alkyl-cyclohex-2-enyl ketones and the corresponding 2-alkylene-cyclohexyl ketones, using as catalyst a ruthenium complex obtainable by the reaction of an appropriate ruthenium organometallic precursor and an acid.
