Abstract

In the majority of scenarios for absolute stereochemical control, the presence of a C, symmetry axis within the chiral auxiliary can serve the very important function of dramatically reducing the number of possible competing, diastereomeric transition states. A number of workers have noted the importance of this symmetry element in their rational design of chiral auxiliaries. Very early, Noyori'utilized 2, 2'-dihydroxy-1, 1'-binaphthyl as an axially ...
