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

ABSTRACT: 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.
