Volatile Monoterpenes as Potential Parent Structures for New Herbicides
Eighteen volatile monoterpenes, which are among the major constituents of essential oils from plants, were screened for phytotoxicity to several crop and weed species. Several monoterpenes containing an oxygen function severely inhibited germination of four different annual weeds while concurrently displaying little effect on soybean germination. Soybeans varied in their sensitivity to various ...
متن کاملCycloadditions of Noncomplementary Substituted 1,2,3-Triazines
The scope of the [4 + 2] cycloaddition reactions of substituted 1,2,3-triazines, bearing noncomplementary substitution with electron-withdrawing groups at C4 and/or C6, is described. The studies define key electronic and steric effects of substituents impacting the reactivity, mode (C4/N1 vs C5/N2), and regioselectivity of the cycloaddition reactions of 1,2,3-triazines with amidines, enamines, ...
متن کاملSynthesis of 2,4,6-tri-substituted-1,3,5-triazines.
Several specific synthetic protocols were developed for the preparation from cyanuric chloride of a range of symmetric and non-symmetric di- and tri-substituted 1,3,5-triazines containing alkyl, aromatic, hindered, chiral and achiral hydroxyalkyl, ester and imidazole groups via sequential nucleophilic substitution of the C-Cl bond by C-O, C-N and C-S bonds.
متن کامل3-Nitro, 1-Amino Guanidine and 5-Hydrazino-1H-Tetrazole Derivatives as New Energetic Materials
The synthesis of 3-amino-1-nitroguanidine (3-ANQ) and 5-hydrazino tetrazole (5-HT) derivatives as new energetic materials are described. Reaction of 3-ANQ with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-HT. Addition of NaN3 to a mixture of 3-ANQ and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excelle...
متن کاملInhibitors of shikimate dehydrogenase as potential herbicides.
The shikimic acid biosynthetic pathway, which operates in micro-organisms and higher plants but not in mammals, leads to several essential amino acids and also to a variety of other metabolites. It was hoped, therefore, that blockage of the pathway might have a damaging effect on plant metabolism, giving a useful commercial herbicide with selective toxicity. Shikimate dehydrogenase, the enzyme ...
