摘要:
Process for the preparation of substituted pyridine derivatives of formula (I) comprising reaction of a α-β-unsaturated carbonyl compound of formula (II) R3—C(O)—C(R1)═C(R2)-G with a Wittig reagent or Horner-Wadsworth-Emmons reagent in the presence of a base and optionally subsequent cyclization.
