Synthesis and Single Crystal Structures of Substituted-1,3-Selenazol-2-amines "2279
نویسندگان
چکیده
The synthesis and X-ray single crystal structures of a series of new 4-substituted-1,3selenazol-2-amines is reported. The efficient preparation of these compounds was carried out by two-component cyclization of the selenoureas with equimolar amounts of α-haloketones. The selenoureas were obtained from the reaction of Woollins’ reagent with cyanamides, followed by hydrolysis with water. All new compounds have been characterized by IR spectroscopy, multi-NMR (1H, 13C, 77Se) spectroscopy, accurate mass measurement and single crystal X-ray structure analysis.

متن کاملSynthesis and solid-state characterisation of 4-substituted methylidene oxindoles
BACKGROUND 4-substituted methylidene oxindoles are pharmacologically important. Detailed analysis and comparison of all the interactions present in crystal structures is necessary to understand how these structures arise. The XPac procedure allows comparison of complete crystal structures of related families of compounds to identify assemblies that are mainly the result of close-packing as well...
