Abstract

Skeleton-expanding operations that provide control of all levels of selectivity are among the most valuable transformations in organic synthesis.[1] One important example is the alkylation of ester or amide enolates which requires either a chiral auxiliary or stoichiometric amounts of a chiral base in order to control the absolute configuration of the final alkylation product.[2–5]
