Synthesis of Unsymmetrical Δ4,4'-2,6-Diphenyl-4-(thiopyranyl)-4H-pyrans

Unsymmetrical Δ4,4'-tetraphenyl-4-(thiopyranyl)-4H-pyran 17 and related compounds have been synthesized.The reversal in the polarity (umpolung) of 2,6-diphenylpyrylium salt 13 is achieved by the synthesis of the Wittig-Horner reagent (11) of di

Synthesis of Unsymmetrical Δ4,4'-Bi-4H-pyrans and -thiopyrans

Unsymmetrical Δ4,4'-bi-4H-pyrans and -thiopyrans are prepared from the Wittig reagent which is derived from (4H-pyran-4-yl)triphenylphosphonium salts or the thio analogues by allowing the reagent to react with a pyrylium or thiopyrylium salt wi
