The method of synthesis of ..beta..-sitosterol-4-/sup 14/C starting with the enolactone 4-oxa-5-sitosten-3-one is discussed. Methyl-/sup 14/C magnesium iodide is utilized for the introduction of the label. The authors selected this method for the isolation of ..beta..-sitosterol-/sup 14/C, introducing a series of changes into the original method. The authors discuss obtaining sitostenone, the ketoacid of sitostenone, the enol-lactone of the ketoacid of sitostenone, sitostenone-4-/sup 14/C (by different methods), the enol-acetate of sitostenone-/sup 14/C, and ..beta.. sitosterol-4-/sup 14/C.
