Minor and trace sterols in marine invertebrates 55. The isolation, structure elucidation and synthesis of ergosta-5,24(28),25-trien-3β-ol
The isolation, structure determination and synthesis of ergosta-5,24(28),25-trien-3β-ol, as well as the synthesis of its 28-14C analog - a possible biosynthetic precursor of several marine sterols - is described.
