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

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 title compound, C 15 H 17 NO 2 S, synthesized as an inhibitor for 5-lipoxygenase, comprises the neutral 1,2-diethyl-3hydroxy-6-phenylthiopyridin-4(1H)-one molecule. The H atom of the hydroxy group and the carbonyl O atom form intermolecular hydrogen bonds with another molecule in a head-to-head
## Abstract 17β‐Hydroxy‐[1ξ,2ξ‐^3^H~2~]4,6‐androstadien‐3‐one was prepared by the selective reduction of 17β‐hydroxy‐1,4,6‐androstatrien‐3‐one in benzene with tritium over 5% palladium on carbon. After purification by thin layer chromatography and high pressure liquid chromatography, the specific a
