Abstract
The Cu-catalyzed novel aerobic oxidative
esterification reaction
of 1,3-diones for the synthesis of α-ketoesters has been developed.
This method combines C–C σ-bond cleavage, dioxygen activation
and oxidative C–H bond functionalization, as well as provides
a practical, neutral, and mild synthetic approach to α-ketoesters
which are important units in many biologically active compounds and
useful precursors in a variety of functional group transformations.
A plausible radical process is proposed on the basis of mechanistic
studies
