Synthesis and structure of substituted 5-phenoxy-1,2,4-dithiazole-3-ones
摘要:
AbstractSeven new substituted 5‐phenoxy‐1,2,4‐dithiazole‐3‐ones were prepared in modest yield (53–76%) from corresponding O‐phenyl thiocarbamates and chlorocarbonylsulfenyl chloride in dry ether at −10 °C. All of the compounds were characterized by NMR and elemental analysis and some of them by X‐ray diffraction. Preliminary kinetic measurements showed that the parent 5‐phenoxy‐1,2,4‐dithiazole‐3‐one is a very efficient sulfurizing agent toward triphenyl phosphite. J. Heterocyclic Chem., (2011)
The invention relates to compounds that have an affinity to the μ-opioid receptor and the ORL 1-receptor, methods for their production, medications containing these compounds and the use of these compounds for the treatment of pain and other conditions.

A method for efficiently producing a cyanogen halide with suppressed side effects, and a method for producing a high-purity cyanate ester compound at a high yield includes contacting a halogen molecule with an aqueous solution containing hydrogen cyanide and/or a metal cyanide, so that the hydrogen cyanide and/or the metal cyanide is allowed to react with the halogen molecule in the reaction solution to obtain the cyanogen halide, wherein more than 1 mole of the hydrogen cyanide or the metal cyanide is used based on 1 mole of the halogen molecule, and when an amount of substance of an unreacted hydrogen cyanide or an unreacted metal cyanide is defined as mole (A) and an amount of substance of the generated cyanogen halide is defined as mole (B), the reaction is terminated in a state in which (A):(A)+(B) is between 0.00009:1 and 0.2:1.
