摘要：

From their NMR spectra, the α- and γ-racemates of the phenylindanes, obtained by acid-induced dimerization of isohomogenol and isosafrole, are shown to possess the 1,2-cis-2,3-trans-and 1,2-trans-2,3-trans-configurations respectively. This conclusion contradicts the configurations previously assigned to these racemates. Metanethole the dimer of anethole is shown to be the γ-racemate, that is, the 1,2-trans-2,3-trans-racemate. The 1,2-cis-2,3-cis-configuration of the synthetic β-racemates of metanethole and diisohomogenol is confirmed. © 1969.
