  Straightforward Access to Pyrazines, Piperazinones, and Quinoxalines by Reactions of 1,2-Diaza-1,3-butadienes with 1,2-Diamines under Solution, Solvent-Free, or Solid-Phase Conditions

  摘要：

  The preparation of tetrahydropyrazines, dihydropyrazines, pyrazines, piperazinones, and quinoxalines by 1,4-addition of 1,2-diamines to 1,2-diaza-1,3-butadienes bearing carboxylate, carboxamide, or phosphorylated groups at the terminal carbon and subsequent internal heterocyclization is described. The solvent-free reaction of carboxylated 1,2-diaza-1,3-butadienes with the same reagents affords piperazinones, while phosphorylated 1,2-diaza-1,3-butadienes yield phosphorylated pyrazines. The solid-phase reaction of polymer-bound 1,2-diaza-1,3-butadienes with 1,2-diamines produces pyrazines.

  The reaction of 1,2-diaza-1,3-butadienes with dibenzyl diisopropylphosphoramidite, methyl tetraisopropylphosphorodiamidite or tris(dimethylamino)phosphane under solvent-free conditions gave stable α-phosphoranylidene-hydrazones that, in turn, were transformed into the corresponding 5-oxo-4-phosphoranylidene-4,5-dihydro-1H-pyrazoles. X-ray diffraction analysis of one of these derivatives is reported

  1,2-Diaza-1,3-dienes readily react as Michael acceptors with thiocyanic acid generated in situ from potassium thiocyanate. The acidic medium of the reaction promotes the intramolecular ring closure of the α-thiocyanato hydrazones allowing access to novel 2-imino-4-thiazolines functionalized at positions 3, 4, and 5 in a one-pot, high-yielding process.

  An 1,2-diaza-1,3-diene's cyclodimerization that provides symmetrical fully substituted 1-amino pyrroles through an unusual formal [3+2] reaction is investigated. The study has demonstrated that the presence of electron withdrawing groups on the terminal carbon atom of the azo-ene system is crucial for the success of the reaction. The synthesis occurs with complete regioselectivity and requires a very

  日期：1988.1

  α-Olefinated carbonyl derivatives have been obtained in good yield under very mild conditions by Wittig-type reaction of some conjugated azoalkenes with carbomethoxymethylene triphenylphosphorane. The reaction mechanism seems to implicate zwitterionic rather than cycloadduct intermediate, as usual for the Wittig reaction.

  zinc(II) triflate‐catalyzed synthesis of highly functionalized pyrroles is described. The sequence involves the preliminary preparation of α‐aminohydrazones by Michael addition of primary amines to 1,2‐diaza‐1,3‐dienes. The treatment of these intermediates with dialkyl acetylenedicarboxylates produces α‐(N‐enamino)‐hydrazones that are converted into the corresponding pyrroles. The substituents on the
