  Pyridinium N-Ylides and (Arylmethylene)azol-5-ones. Reaction Cascade Leading to an Unusual Spiroisoxazolinone Ring

  摘要：

  The reaction of a series of (arylmethylene)azol-5-ones with phenacylpyridinium salt 3 in glacial acetic acid/ammonium acetate mixture gives different results depending on the starting azolone. The isoxazol-5-ones 1 give the unusual spirans 6 in a reaction cascade involving Michael- and retro-Michael reactions, C-alkylation, aldol addition, and diastereospecific cyclization. The reaction performed with oxazol-5-ones 11 has shown that a literature re po rt has to he corrected since no oxazolopyridines 12 hut rather arylideneimidazol-5-ones 13 are produced. In the case of pyrazolin-5-ones 14, the unavoidable formation of bis-adducts 15 always prevents any other type of reaction. (C) 2000 Elsevier Science Ltd. All rights reserved.

  derivatives are reported and are shown to have the expected different tautomeric arrangements. The unusual features of the NH-tautomer (3e) were interpreted in terms of the RAHB (resonance-assisted hydrogen bond) model and its relative stability was investigated by ab initio and DFT calculations.

  spirocyclic compounds bearing three contiguous stereocenters and high functionalization were obtained through a formal [3+2] cycloaddition reaction catalyzed by a cooperative system. The spiro compounds were synthesized from 4‐arylideneisoxazol‐5‐ones and isocyanoacetate esters using a bifunctional squaramide/Brønsted base organocatalyst derived from a Cinchona alkaloid and silver oxide as Lewis acid. This method
