摘要:

Abstract21‐Fluoropregnenolone‐3‐acetate‐21‐18F (4b) and 21‐fluoropregnenolone‐21‐18F (8) were synthesized by nucleophilic substitution of the iodo group of the corresponding 21‐iodo analogs by F‐fluoride in an acetonitrile solution of 18‐Crown‐6. 21‐Fluoropregnenolone‐3‐acetate‐ 7‐3H (10b) and 21‐fluoropregnenolone‐7‐3H (9b) were synthesized by reacting 21‐ethoxalyl pregne
