The present disclosure provides a functionalized olefin-based polymer, a process for producing the same, and articles containing the functionalized olefin-based polymer. The functionalized olefin-based polymer includes an olefin-based polymer, and a functional agent grafted to the olefin-based polymer by way of a coagent. The coagent is either a cinnamoyl derivative and/or a cyano-acrylate compound. The presence of the coagent inhibits a change in the molecular weight during radical functionalization of the olefin-based polymer.
Synthesis of Dihydrouracils Spiro-Fused to Pyrrolidines: Druglike Molecules Based on the 2-Arylethyl Amine Scaffold
The synthesis of a small library of dihydrouracils spiro-fused to pyrrolidines is described. These compounds are synthesized from b-aryl pyrrolidines, providing products with the 2-arylethyl amine moiety, a structural feature often encountered in compounds active in the central nervous system. The b-aryl pyrrolidines are synthesized through a three-step methodology that includes a Knoevenagel condensation reaction, a 1,3-dipolar cycloaddition reaction, and a nitrile reduction.
