摘要：
Synthesis of 2‐Oxo‐2H‐pyran‐5‐carboxylate Derivatives 3‐Substituted diethyl pent‐2‐enedioates are easily formylated by means of ethyl formate/TiCl4/4‐methylmorpholine to produce the ethoxymethylene derivatives, which are smoothly cyclized either with HCOOH or PPA to corresponding 2‐oxo‐2H‐pyran‐5‐carboxylate derivatives.
