Abstract
The l-amino acid oxidase of Mytilus edulis has been used to oxidize l-lysine on a large scale in the presence of catalase. The α-oxo acid derived from lysine cyclizes to a Schiff base, which readily dimerizes. The dimer undergoes spontaneous dehydration and decarboxylation to form 1,2,3,4,5,6,7,8-octahydropyrido[3,2-a]-indolizin-10(4bH)-one. This structure was established by a study of its molecular weight and infrared, nuclear-magnetic-resonance and mass spectra.
