Abstract

Ruthenium-catalyzed hydroamidations of alkynes allow a concise synthetic entry to both E- and Z-configured enamide natural products. This was demonstrated by the synthesis of botryllamides C and E, lansiumamides A and B, and lansamide I in 1-3 steps and 57-98% yield from simple, commercially available precursors.
