Enolization requirements for

Braun s HYTRA reagent ((/ )- or (5)-2-hydroxy-l,l, 2-triphenyl acetate) is derived by simple transformations from inexpensive and enantiomerically pure methyl man-delate. Double deprotonation of the chiral acetate with EDA generates the enolate required for addition to aldehydes. The diastereomeric ratio observed ranges typically between 10 1 and 12 1. When the corresponding magnesium salts are...
