Biosynthesis of 2-aminobenzaldehyde in flowers of Robinia pseudoacacia and Philadelphus coronarius.
Feeding experiments with 13C- and fluorine-labelled precursors were performed to reveal the biosynthesis of 2-aminobenzaldehyde in flowers of Robinia pseudoacacia and Philadelphus coronarius. The results are in agreement with the transformation of anthranilic acid to indole followed by oxidative ring opening and hydrolysis of the resulting N-formyl-2-aminobenzaldehyde. This route differs from that observed in Hebeloma sacchariolens (Basidiomycetes) in which anthranilic acid is directly reduced to 2-aminobenzaldehyde.
