摘要：
A facile synthesis of 17 alpha-hydroxy steroids with perfluoroalkylsulfonyl fluoride as hydroxyl activating agent was reported. The method features mild (40 degrees C), rapid (0.5 h), high yield, and high functional group tolerance. Notably, the method is applicable to HCOOH and CF3COOH, unusual and synthetically useful nucleophiles in hydroxyl inversion reaction. (C) 2015 Elsevier Ltd. All rights reserved.
