The four isomeric 7-isopropyl-4-hydrindanones (2)-(5) have been prepared and their configurations assigned, using arguments based on the results of equilibration of the two pairs of ketones and on the products formed on hydrogenation of enone precursors.Base-catalysed equilibration at ca. 22 degC indicates that for (3)(2), -ΔG4.5 kcal mol-1 and for (5)(4), -ΔG ca. 0.1 kcal mol-1.Possible diagnostic features in the 1 H n.m.r. spectra of (2)-(5) are discussed briefly.
