Abstract
The steroid (5'R, 17R)-11β-hydroxy-5'-methylspiro-[androst-4-ene-17,2'-[1,4]dioxane]-3,3',6'-trione (cortienic acid lactide), C 23 H 30 O 6 , adopts an arched conformation towards the β side of the molecule. The spiro lactide ring is in the half-chair conformation, with the two ester carbonyl groups aligned and directly opposing each other. A hydrogen bond between the hydroxyl group of ring C and the carbonyl group of ring A links the molecules, forming chains along b.
