(22E,24R)-5α-Ergosta-2,22-dien-6-one

In the title mol­ecule, C(28)H(44)O, two six-membered rings have regular chair conformations, while the six-membered ring containing the C=C double bond exhibits a distorted chair conformation. The five-membered ring adopts an envelope conformation. In the crystal, weak inter­molecular C—H⋯O inter­a...

description In the title mol­ecule, C(28)H(44)O, two six-membered rings have regular chair conformations, while the six-membered ring containing the C=C double bond exhibits a distorted chair conformation. The five-membered ring adopts an envelope conformation. In the crystal, weak inter­molecular C—H⋯O inter­actions link mol­ecules into chains along the b axis. The absolute configuration was assigned to correspond with that of the known chiral centres in a precursor mol­ecule.
