A new approach to remote asymmetric induction in the diastereoselective reduction of γ-keto esters by use of a chiral podand as chiral auxiliary
Abstract
An efficient 1,7-asymmetric induction was achieved with up to 82% diastereoisomeric excess (d.e.) in the diastereoselective reduction of the γ-keto ester 4 and o-acetylbenzoate 6 using the chiral podand 2 as chiral auxiliary.
