摘要:
The fungicidal compound 4,5-dimethyl-N-2-propenyl-2-(trimethylsilyl)-3-thiophenecarboxamide (Formula (I)) has shown superior and unexpected control of the growth of the soil-borne fungus Gaeumannomyces graminis (Gg). The present invention provides a novel compound for synthesizing the compound of Formula (I) which uses the compound 4-hydroxy-4,5-dimethyl-2-trimethylsilanyl-dihydrothiophene-3-carboxylic acid allylamide (Formula (II)) as well as novel compounds of synthesizing the allylamide. In addition, Formula (II) itself has unexpectedly been found to provide control of Gg. Therefore, the compounds having Formula (III): or an agronomic salts and compositions thereof are expected to provide such control as well; wherein: Q is —NH, S, or O; W is O, or S; X is —OH, —OAc, —OR, where R is lower alkyl; Y is S, O, or —NH; Z is —Si(R)3, —C(R)3, where R is lower alkyl; R1 is a lower alkyl, allyl, or propargyl; R2 is a lower alkyl or aryl; and R3 and R4 are independently chosen from hydrogen, a lower alkyl and aryl; optionally, R2 and R3 together form a 5- or 6-membered ring.

摘要:
The present invention is directed to novel cyclic nitrones and their use in the prevention of oxidation tissue damage by free radicals, their use in the treatment of a number of disease states in which radicals either damage or destroy tissues via oxidation, and pharmaceutical compositions containing these cyclic nitrones.
摘要:
Fungicides having thiophene rings may be made from the intermediate compound 3-carbomethoxy-4,5-dimethylthiophene. That compound, and related compounds, may be produced by reacting an alpha mercaptoketone, e.g., 3-mercapto-2-butanone, with an acrylate, e.g., methyl-3-methoxy acrylate, in the presence of an alkoxide base, e.g., NaOMe, to form the substituted tetrahydrothiophene, followed by conversion to the aromatic thiophene with an acid treatment. The substituted tetrahydrothiophene is a novel compound.
