Abstract
Methods of synthesis of dienic δ-alkoxy-α, α-dicarbonyl-substituted compounds were experimentally examined. The structure of the synthesized compounds was studied by1H and13C-NMR methods. It was shown that the δ-alkoxy diesters are present in equilibrium with 2H-pyrans, while δ-alkoxy-γ-methyl diesters and 2-(3′-alkoxypropen-2′-ylindene)indanediones exist in an open form and do not undergo cyclization into 2H-pyrans.
