research Highly efficient nucleophilic addition of alkyl Grignard reagents to 17-ketosteroids in the presence of cerium(III) chloride: Synthesis of 17α-propyl-17β-hydroxy-4-androsten-3-one, an androgen receptor antagonist
Adding cerium(III) chloride to Grignard reagents improves the making of compounds that could treat prostate issues and hair loss.
