Abstract:
A process for cyanating an aldehyde is provided. The process comprises reacting the aldehyde with: i) a cyanide source which does not comprise a Si-CN bond or a C-(C=O)-CN moiety; and ii) a substrate susceptible to nucleophilic attack not comprising a halogen leaving group; in the presence of a chiral catalyst. Preferably, the chiral catalyst is a chiral vanadium or titanium catalyst. The cyanide source is preferably an alkali metal cyanide and the substrate susceptible to nucleophilic attack not comprising a halogen leaving group is a carboxylic anhydride.

Abstract:
The invention relates to carboxylic acid-2-acyloxymethyl-4-aminobutyl esters of the general formula (I), which are intermediate products important for the introduction of the side-chain in antiviral purine derivatives. These compounds are produced by hydrogenation of cyano esters of the general formula (III).
Abstract:
The present invention provides enzymatic processes for preparing optically active compounds of Formula (I) wherein X, E and * have the meanings defined in the specification. The invention also provides chiral intermediates useful for preparing compound of Formula (I) and enzymatic processes for preparing such chiral intermediates.
Abstract:
Compounds and methods for mitigating neurodegeneration, effecting neuroprotection and/or effecting cognition enhancement in a subject are described. Neurological or cognitive conditions are treated by administering to a subject an effective amount of a therapeutic compound comprising a nitrate ester, or a pharmaceutically acceptable salt or ester thereof.
Abstract:
The present invention relates to fragrance delivery systems which comprise: a) one or more pro-fragrances having formula (I) wherein G and G are methyl, or a cyclic hydrocarbyl unit derived from the isomers of ionone and/or damascone; R and R are each independently C1-C22 substituted or unsubstituted, branched or unbranched alkyl, C2-C22 substituted or unsubstituted, branched or unbranched alkenyl, C2-C20 substituted or unsubstituted, branched or unbranched hydroxyalkyl, C7-C20 substituted or unsubstituted alkylenearyl, C3-C20 substituted or unsubstituted cycloalkyl, alkyleneoxy; C6-C20 aryl, C5-C20 heteroaryl comprising one or more heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur, and mixtures thereof; two of the units Y , Y , R or R can be taken together to form one or more aromatic or non-aromatic, heterocyclic or non-heterocyclic, single rings, fused rings, bicyclo rings, spiroannulated rings, or mixtures thereof, said rings comprising from 3 to 20 carbon atoms and one or more heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur, and mixtures thereof; b) one or more aldehyde releasing oxazolidine pro-fragrances; and c) the balance carriers, pro-fragrances, pro-accords, other perfume ingredients.
Abstract:
The invention relates to a process for the preparation of such isomer mixtures of cypermethrine of formula (I), wherein carbon atoms indicated by 1,3 and α stand for a chiral carbon atom and the wavy line indicates cis or trans configuration related to the cyclopropane ring - which contains out of the theoretically possible 8-isomers of cypermethrine at least 95 % of 1RtransS and 1StransR (Ib) isomer pair or only a mixture of 1RcisS and 1ScisR (Ia) and the isomer pair (Ib) of the ratio (Ia):(Ib) = 55:45 - 25:75 by asymmetric transformation of second order performed in the presence of an amine base and solvent from a starting cypermethrine isomer mixture which contains next to the isomer pair (Ib) cis and other trans isomers or the isomer pair Ia + Ib at an undesired ratio.
