Abstract
N'-Substituted N-furfuryloxamides (4) were prepared via condensation of potassium methyl oxalate (8) with furfurylamine (5f) using 1, 1'-oxalyldiimidazole (6), followed by hydrolysis of the resulting amide-ester (10), and finally condensation with aliphatic or aromatic amines (5). The prepared compounds (4) were examined for activity as plant growth regulators using two kinds of plant seeds, namely, those of rape, Brassica campestris L. (Dicotyledoneae) and leek, Allium tuberosum ROTTLER (Monocotyledoneae). N'-Benzyl- and N'-phenyl-N-furfuryloxamides (4b and 4c) and N, N'-difurfuryloxamide (4f) inhibited root growth in seedlings of both species.
