✦ Synopsis

In the title molecule, C~21~H~31~ClO~4~, rings A, B and C have regular chair conformations, while ring D has an envelope form. In the crystal structure, weak intermolecular C—H...O hydrogen bonds link the molecules into zigzag chains running along the b axis.

The ring conformation of the title compound, C 19 H 30 O 3 , is similar to that of the 5-epimer except for the cis A/B ring junction. Ring D adopts a 13,14-half chair conformation. The molecules are linked together by a two-dimensional network of hydrogen bonds involving the carbonyl and hydroxyl gr
