Sequential addition of iBu2AIH and RLi or RMgX to Schiffbase esters derived from amino acids provides a simple route to β-amino alcohols. The reaction procedes without racemization, and with high threo selectivity. Several representative sphingosines are synthesized.
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.
