Acid controlled generation of indanes and oxazolines from β-hydroxyarylethanamide
摘要:
Simple and efficient protocols for the construction of substituted indanes and oxazolines through intramolecular cyclization of beta-hydroxyarylethanamide using trifluoromethanesulfonic acid and titanium tetrachloride in 1,2-dichloroethane respectively have been described. The selectivity due to different acid catalysts was explored and optimized to achieve good to excellent yield. (C) 2013 Elsevier Ltd. All rights reserved.
