Abstract
AbstractProton and carbon‐13 nmr spectra for cis‐ and trans‐2‐ethyl‐3,3‐diphenyl‐4‐methyltetrahydrofurans and 2‐ethylidene‐3,3‐diphenyl‐4‐methyltetrahydrofuran, derived from the pyrolysis of the quaternary ammonium salts of the diastereomeric isomethadols and isomethadone, respectively, are reported. 1H and 13C chemical shifts and 1H‐1H coupling constants have been assigned in each case. The isomeric teterahydrofurans have been analyzed in terms of a half‐chair conformation, and an envelope conformation for the ethylidene derivative.
