摘要:
Novel alkyl 2,3,3-triiodoallyl ethers useful as disinfectants are provided by an addition reaction of alkyl-3-iodo-2-propinyl ethers with iodine. The starting alkyl-3-iodo-2-propinyl ethers can be prepared by a new process comprising an alkylation of propargyl alcohol with an alkyl sulfate or alkyl sulfonate in the presence of an alkali, followed by monoiodization of the resulting alkyl-2-propinyl ether. This invention also provides a composition comprising alkyl 2,3,3-triiodoalkyl ethers useful as a poultry feed additive having growth increasing effects and for treating swine scours.
摘要:
A new derivative of the macrolide antibiotic SF-837 substance is manufactured by treating a 9,2'-diacyl- or 9-acyl-SF-837 composition with dimethylsulfoxide and acetic anhydride, and, subsequently, with an alcohol or water-containing solvent to yield the novel compound, 9-Acyl-3"-thiomethoxymethyl-SF-837 composition. In addition to high therapeutic effectiveness and low acute toxicity, this novel compound of the present invention has the great advantages that it does not have the bitter taste originally accompanying the parent compounds, and the further advantage that it is suitable for pediatric and veterinary use.
