Giang T. Hoang, Venkata Jaganmohan Reddy, Huy HK Nguyen, and Christopher J. Douglas* β-Alkoxyketones are common intermediates in organic synthesis. An unusual approach to this class of compounds could be the insertion of a C= C bond into an ester, a potentially atom economical process (Scheme 1). This alkene “oxyacylation” could be an alternative to the aldol reaction.[1] Atom economy and ester manipulation, however, are ...
