| Abstract: | The “normalizing factor” for the tomato mutant “chloronerva” was shown to possess the structure of (2S:3'S':3''S)-N- N-(3-amino-3-carboxypropyl)-3-amino-3-carboxypropyl]-azetidine-2-carboxylic acid (1) and proved to be identical with nicolianamine, especially on the basis of high resolution mass, 1H, and 13CNMR spectroscopie investigations of 1 as well as of its tetra-(trimethylsilyl), di-(4-bromobenzoyl) (trimethyl ester (3), 4-bromobenzoyl dimethyl ester, and diacetyl methyl ester (4) derivatives. 1 seems to be of general occurrence in higher plants and is considered a possible phytosiderophore with an essential function in the cellular iron transport and/or metabolism. |
