Abstract:
The invention relates to α-sulfonylamino-acetonitrile derivatives of the general formula (I) including the optical isomers thereof and mixtures of such isomers, wherein Ar1, and Ar2 independently of each other stand for an optionally substituted aryl or heteroaryl group, R1, and R2 stand independently of each other for hydrogen, optionally substituted C1,-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; R3 designates hydrogen, C3-C5alkenyl, C3-C5alkynyl or optionally substituted C1,-C5alkyl; R4 is optionally substituted C1,-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; R5 and R6 are independently of each other hydrogen or optionally substituted C1-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; R7, and R8 are independently of each other hydrogen or optionally substituted C1,-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; W designates a bridge selected from —O— —S(O)m— or —NR3—; X designates a direct bond or a bridge selected from —O—, —S(O)m— or —NR3—; a and b independently of each other stand for a number 1, 2 or 3; and c and m independently of each other stand for a number zero, 1 or 2. These compounds possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi.
Abstract:
Disclosed are compounds of formula I having a strong musk-like odor: In formula I, R1 and R2 are hydrogen or methyl, with the proviso that when R1 is methyl, R2 is hydrogen, and when R1is hydrogen, R2 is methyl. The compounds of formula I may be in the Z- and/or in the E-form. Methods of making the compounds of formula I and compositions containing such compounds are also disclosed.
Abstract:
The invention is concerned with odorant compositions which contain macrocycles, namely 15- to 17-membered compounds of the formula: wherein the dotted line signifies an optional additional bond, X and Y stand for methylene or C2-12-polymethylene, optionally substituted with an additional methyl group, and A signifies hydrogen or methyl in the case of the unsaturated compounds and methyl in the case of the saturated compounds, with the proviso that the unsaturated compounds are present to more than 80% in the cis form when A signifies hydrogen and are present to more than 50% in the cis form when A signifies methyl, with the exception of Z-oxacyclopentadec-6-en-2-one (15-membered ring), Z-oxacycloheptadec-8-en-2-one (17-membered ring), and Z-oxacycloheptadec-11-en-2-one (17-membered ring), a process for the manufacture of the compounds of formula I and the use of the compounds of formula I as odorants.
Abstract:
The invention relates to N-sulfonyl-α-amino-acetic acid derivatives of the general formula (I): including the optical isomers thereof and mixtures of such isomers, wherein Ar1 and Ar2 independently of each other stand for an optionally substituted aryl or heteroaryl group, R1 and R2 stand independently of each other for hydrogen, optionally substituted C1-C5alkyl, optionally substituted C2-C5alkenyl, C-2C5alkynyl or optionally substituted C3C6Cycloalkyl; R3 designates hydrogen, C-3C5alkenyl, C3-C5 alkynyl or optionally substituted C1-C5alkyl; R4 is optionally substituted C1-C5alkyl, optionally substituted C-2C5alkenyl, C-2C5aklynyl or optionally substituted C-3C6 cycloalkyl; R5 and R6 are independently of each other hydrogen or optionally substituted C1-C5alkyl, optionally substituted C2-C5alkenyl, C-2C5alkynyl or optionally substituted C3-C6cycloalkyl; R7 and R8 are independently of each other hydrogen or optionally substituted C1-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; W designates a bridge selected from —O—, —S—, —SO—, —SO2— or is an —NH— or —N(C1-C5alkyl)-bridge; X designates a direct bond or a bridge selected from —O—, —S—, —SO—, —SO2— or is an —NH or —N(C1C5alkyl)-bridge; Y designates —OR9 or NR10R11; a and b independently of each other stand for a number 1, 2 or 3; and c stands for a number zero, 1 or 2; with R9, R10 and R11 being defined according to the claims. These compounds possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi.
Abstract:
The invention includes (6E)- and (6Z)-isomers of 3,6-dimethyloct-6-en-1-ols and 6-ethyl-3-methyloct-6-en-1-ols and their mixtures. The mixtures are free from their corresponding oct-5-ene double bond isomers. Processes of preparing odorant compositions containing these compositions are also provided.
Abstract:
The invention relates to compounds of the general formula wherein R1, R2, R3, R4, R5, X1, X2, X3, m and n have the significances given in claim 1, and optionally the enantiomers thereof. The active ingredients have advantageous pesticidal properties. They are especially suitable for the control of pests on domestic and farm animals.
