  • Process for the preparation of ibodutant (MEN15596) and related intermediates
    Patent number: 8431684
    Abstract: This invention relates to a novel process for synthesizing the product ibodutant shown in the figure below, consisting of a small number of high-yield steps involving reagents and solvents with low environmental impact, characterized by the coupling of two portions, compounds (3) and (4), one of which (3) is synthesized by coupling of 6-methyl-2-benzo[b]thiophenecarboxylic acid (1) with 1-amino-alpha-alpha-cyclopentan carboxylic acid and subsequent cyclization with oxazolone, while the other, compound (4), is obtained from suitable highly selective functionalizations of 4-aminomethylpiperidine (2).

  • Gellable aqueous compositions containing polymers with special chelating functional groups useful for recovering oil from an oil field
    Patent number: 5256315
    Abstract: Gellable compositions containing:(a) water;(b) a water-soluble organic polymer bearing special chelating functional groups;(c) a multi-valent metal ion capable of causing the polymer to crosslink,are useful to recover oil from a oil field.Said compositions make it possible gels to be obtained which are endowed with improved physical properties and show a higher stability under the conditions prevailing in the oil field.
