  Synthesis of a Pyrazole Isostere of Pyrroles Formed by the Reaction of the .epsilon.-Amino Groups of Protein Lysyl Residues with Levuglandin E2

  摘要：

  A pyrazole isostere of pyrroles that are formed in the reaction of levuglandin E(2) (LGE(2)) with proteins was prepared. The heterocycle was generated, together with a structural isomer, by condensation of a monoalkylhydrazine with a 1,3-diketone. Structures of the isomeric pyrazoles were established by NOE experiments. Coupling with proteins to provide antigens was achieved in the presence of alkene, carboxyl, and allylic hydroxyl functionality by reductive alkylation with an aldehyde group at the end of an n-alkyl tether to the 1-position of the pyrazole isostere.
