Chemistry of Heterocyclic Compounds Aims and scope

Abstract

2-Ethyl substituted isoflavones have been synthesized. 7-Isopropyloxyisoflavones carrying 1,3-benzodioxole and 1,4-benzodioxan nuclei have been obtained from them. The spectral characteristics of the compounds obtained are discussed. The reaction of several of the products with various lanthanide shift reagents (LSR) has been studied. The preferred conformation of compounds in solution has been determined. It was shown that optically active LSR must not be used for obtaining quantitative data on the molecular conformation of a substrate due to the lack of effective axial symmetry in the adduct.
