The enamine aldehydes RC(=CHNMe2)CHO (R = Et or Ph) were condensed with the bis-enolate CH2=C-(O-)CH=C(O-)OEt to give the title aromatic compounds.Thus these products are available from the acetals R1CH2CH(OR2)2 (R1 = R2 = Et; R1 = Ph, R2 =Me) in two steps.The Vilsmeier formylation of the several derivatives of butanal was examined.
