  Methylenepyran unsaturated Fischer carbene complexes from γ-methylpyrylium salts and alkynylcarbenes. Evolution to spiro-pyran-cyclopentenone compounds

  摘要：

  Push-pull methylenepyran compounds 3 containing ferrocenyl or aryl groups are synthesized from reaction of condensation between gamma-methyl-pyrylium salts 1 as precursors of gamma-methylenepyrans and alkynylcarbene complexes 2 as Michael-type acceptors. The new carbenes 3 evolve in CH2Cl2 Solution at room temperature to provide spiro-fused-pyran-cyclopenten e none 4 and polysubstituted cyclopentenones 5. (C) 2009 Elsevier Ltd. All rights reserved.
