Diazo Esters Addition to Trifluoropyruvamides: New Access to Highly Functionalized Trifluoromethyl Epoxides and Diazo Compounds
Further Information
Publication History
Publication Date:
31 December 2000 (online)
Trifluoropyruvamides in their hydrated form readily react with diazo esters affording new trifluoromethyl epoxides. Activating the pyruvamide with trifluoroacetic anhydride leads to a complete change in selectivity with the formation of a new diazo compound.
