Diaryl-Substituted Polyethers with Acetoacet-Anilide Fragment in the Synthesis of Dihydro-Pyrimidine-Containing Podands*

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

The interaction of ortho-aminoaryl polyethers, derivatives of mono-, di-, and triethylene glycol, with acetyl ketene, generated from 2,2,6-trimethyl-4H-1,3-dioxin-4-one produced acetoacetanilide- containing podands. 2,2,6-Trimethyl-4H-1,3-dioxin-4-one reacted with aminoaryl-substituted podands containing a short polyether chain (1-2 atoms) in toluene medium without catalyst. Acetoacetanilide- containing podands with longer polyether chains could be obtained by using triethylamine or acetic acid as catalyst. Acetoacetanilide-containing podands were used in the Biginelli reaction as СН-active components.
