Stereochemistry and equilibrium relations of dimethyl-(1,2-cyclopentano) phenanthrenes
Abstract 1. Comparison of the relative thermodynamic stability of triaromatic C19 steranes and dimethyl-substituted indans and cyclopentanes has made it possible to establish the three-dimensional structure and the order of elution of dimethyl-(1,2-cyclopentano)phenanthrenes: 3′,3′-, 3′,5′-cis, 3′,4′-trans, 3′,5′-trans, 3′,4′-cis. 2. 1,2- and 1,3-dimethylindans were synthesized by methylenation. The equilibrium concentrations of geometric isomers of synthesized hydrocarbons and the order of their yield were established by means of configurational isomerism. The mass spectra of the obtained dimethylindans are given.
