Feeding experiments with 13C- and fluorine-labelled precursors revealed that the biosynthesis of 2-aminobenzaldehyde in flowers of Robinia pseudoacacia and Philadelphus coronarius is realized by transformation of anthranilic acid to indole followed by oxidative ring opening and hydrolysis of the resulting N-formyl-2-aminobenzaldehyde. \\ | Feeding experiments with 13C- and fluorine-labelled precursors revealed that the biosynthesis of 2-aminobenzaldehyde in flowers of Robinia pseudoacacia and Philadelphus coronarius is realized by transformation of anthranilic acid to indole followed by oxidative ring opening and hydrolysis of the resulting N-formyl-2-aminobenzaldehyde. \\ |
