چکیده

In the title mol-ecule, 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 inter-molecular C-H⋯O inter-actions link mol-ecules into chains along the b axis. The absolute configuration was assigned to correspond with that of the known chiral centres in a precursor mol-ecule.

(22E,24R)-3α,5-Cyclo-5α-ergosta-22-en-6-one

In the title mol-ecule, C(28)H(44)O, the two six-membered rings have a chair conformation and the two five-membered rings haveenvelope conformations. The crystal packing exhibits no short inter-molecular contacts. The absolute configuration was assigned to correspond with that of the known chiral centres in a precursor molecule, which remained unchanged during the synthesis of the title compound.
