Synthesis of Chiral Aminophenols Based on Proline and Their Application in Enantioselective Addition of Diethylzinc to Aldehydes
Synthesis of Chiral Aminophenols Based on Proline and Their Appli-cation in Enantioselective Addition of Diethylzinc to Aldehydes
【摘要】 <正> Three 2-{(3R,7As)-1,1-disubstituted-tetrahydro-1 H-pyrrolo[1,2-c][1,3]oxazol-3-yl}phenols have been synthesized fromsalicylaldehyde and amino alcohols derived from L-proline,andused as ligands in enantioselective addition of diethylzinc toaldehydes,the ee values of obtained secondary alcohols werefound in the range of 0-90%.
