Abstract

The four possible stereoisomers of 3‐methoxy‐16‐methyloestra‐1,3,5(10)‐trien‐17‐ol (1, 2, 3, 4) were converted into the corresponding 16‐methyl‐19‐nortestosterone analogs (5, 6, 7, 8), which were characterized by their ^1^H‐ and ^13^C‐NMR spectra. The coupling constants J~16,17~ and the characteristic ^13^C signals (C‐12, C‐17, C‐18, 16‐CH~3~) clearly confirmed the configurations at C‐16 and C‐17.

## Abstract The four possible isomers of 16‐hydroxymethyl‐3‐methoxyestra‐1,3,5(10)‐trien‐17‐ol 5a, 6a, 7a, 8a were converted into the corresponding 16‐methyl analogues 4a, 11a, 12a, 13a, which were characterized from their ^1^H‐ and ^13^C‐NMR spectra. The results permit a configurational correlatio
