Abstract
The synthesis and the chemical, physical and spectral properties of glycino-N-methylphosphonic acid derivatives, i.e., 1-(N-carbethoxymethyl)-aminocyclopropan-1-phosphonic acid (5), 2-dihydroxyphosphonyl-N-carboxymethylpyrrolidine (10), 5-dihydroxyphosphonylproline (13), 2-carboxy-6-dihydroxy-phosphonyl-piperidine (16), N-(dihydroxyphosphonylmethyl)-proline (18a), N-(dihydroxyphosphonyl-methyl)-piperidin-2-carbonic acid (18b), N-phosphonomethylsubstituted-1-aminocyclopropyl-1-carbonic acid derivatives (21, 22, 23, 24), and 1-(N-dihydroxyphosphonylmethyl)-aminocyclohexan-1-carbonic acid (26) are described. None of these compounds showed herbicidal or plant growth regulator properties. 1-Aminocyclopropyl-1-phosphonic acid (3c) releases ethylene in the presence of oxidizing agents.
