Acta Crystallographica Section E
Methyl-3-oxochola-1,4,22-trien-24-oate, C 25 H 34 O 3 , is a naturally occurring steroid, the con®guration at C20 of which has not yet been determined. Here we report the synthesis and the crystal structure analysis via X-ray diffraction of the 20Repimer. Comparison with data reported for the natural product indicates a different con®guration.
