Abstract - Complete signal assignment was made in the 13C and 1H NMR spectra of racemic 3-methoxy-
6-oxa-8-isoestra-1,3,5(10)-trien-17b-yl acetate. Spectral criteria were established which allow structurally
related 6-oxa analogs of steroidal estrogens to be attributed to the same stereochemical series.
