We report isolation and structure elucidation of AsLn5, AsLn7, AsLn11 and AsLn12: novel luciferin analogs from the bioluminescent earthworm Fridericia heliota. They were found to be highly unusual modified peptides, comprising either of the two tyrosine-derived chromophores, CompX or CompY and a set of amino acids, including threonine, gamma-aminobutyric acid, homoarginine, and unsymmetrical N,N-dimethylarginine. These natural compounds represent a unique peptide chemistry found in terrestrial animals and rise novel questions concerning their biosynthetic origin.

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.
