Abstract	The synthesis of N-methoxyascorbigen (neoascorbigen) — a natural substance from plants of the Cruciferae family — and also N-ethoxyascorbigen is described. In an acidic media under drastic conditions N-alkoxyascorbigens undergo transformations with the release of ascorbic acid and the formation of oligomers of 1-alkoxy-3-methyleneindolenine or with opening of the lactone ring, decarboxylation, and dehydration and the formation of 2-hydroxy-3-(1-alkoxy-3-indolyl)-4-hydroxymethylcyclopent-2-enone. Amides of neoascorbigen, 3-O-methylglycoside of N-ethoxyascorbigen, and the product of the reduction of N-ethoxyascorbigen by sodium borohydride were obtained for the first time.
