摘要:
2,5-dihydrothiazoles are prepared by reacting aza-alkylene-dienes with sulfur at relatively low temperatures for example below about 160.degree. C. Where the reaction is carried out at relatively higher temperature, for example above about 160.degree. C., such as 160.degree. to 250.degree. C., 4,5-dihydrothiazoles are formed. In addition 2,5-dihydrothiazoles can be converted to 4,5-dihydrothiazoles by heating them to temperatures above about 160.degree. C.

摘要:
This invention relates to novel heterocyclic fungicides which are effective in controlling a broad spectrum of phytopathogenic fungi found in the four main classes of fungi namely Phycomycetes, Ascomycetes, Fungi Imperfecti, and Basidiomycetes. Certain of these compounds are especially effective in controlling sclerotial forming fungi such as Whetzelinia sclerotiorum=(Sclerotinia sclerotiorium) and Botrytis cinerea.

Quinolinecarboxylic acid derivatives, such as compound 7-fluoro-8-(4-methyl-1-piperazinyl)-5-oxo-1,2-dihydro-5H-thiazolo(3,2-a)-quinoline-4-carboxylic acid, a pharmaceutical composition containing the same and methods of treatment of bacterial and fungal infections using the same.
摘要:
Novel 2-nitro-5-phenoxyphenyloxazoles, -oxazines and -thiazoles are disclosed. These compounds have the formula ##STR1## wherein A is a C.sub.2 -C.sub.3 alkylene or C.sub.2 -C.sub.3 alkenylene radical which can be substituted by C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 haloalkyl, each of R.sub.1, R.sub.2 and R.sub.3 independently is hydrogen, halogen, trifluoromethyl, nitro or cyano, and X is oxygen, sulfur or an imino group. The novel compounds have herbicidal and plant growth-inhibiting properties. They are especially suitable for use as selective herbicides in crops of cereals.
摘要:
The present invention discloses novel 6-acylamino-2,2-dimethyl-3-phosphonopenams and certain lower alkyl esters thereof possessing antibacterial activity, methods for their production, and intermediates therefor; the production comprises the steps of reacting 6-triphenylmethylamino-2,2-dimethylpenam-3-carboxylic acid with lead tetraacetate to form the corresponding 3-acetoxy compound, the latter is converted to .alpha.-triphenylmethylamino-5,5-dimethyl-3-thiazoline-2-acetic acid which is condensed with dimethyl phosphite to produce .alpha.-triphenylmethylamino-5,5-dimethyl-4(0,0-dimethylphosphono)-thiazolidine-2-acetic acid which is cyclized to 6-triphenylmethylamino-2,2-dimethyl-3-(0,0-dimethylphosphono)penam and the latter is subsequently deblocked and acylated.
