Synthesis, characterization, and biological activities of novel (Z)-3-((E)-1-(alkyloxyimino)ethyl)-5-arylidene-4-hydroxypyrroline-2-one derivatives

Twenty-four novel tetramic acid derivatives (Z)-3-((E)-1-(alkyloxyimino) ethyl)-5-arylidene-4-hydroxypyrroline-2-ones 6a-x were synthesized by the reaction of (Z)-3-acetyl-5-arylidene-4-hydroxypyrroline-2-ones 4 with O-alkyl hydroxylamines 5 under reflux conditions in good yields (77.2-92.4%). Their structures were confirmed by IR, 1H-NMR, MS, and elemental analysis. The preliminary bioassays showed that most of the title compounds exhibited noticeable fungicidal activities against Colletotrichumorbiculare and a certain degree of fungicidal activities against Fusarium gramineaum and Rhizoctonia cerealis at a concentration of 100 μg/mL.

A TECHNIQUE FOR MODIFICATION OF A BIO-PRODUCT MOLECULE AND APPLICATION OF WEED CONTROL

A series of herbicidal molecules derived from 3-acetyl-4-hydroxy-5-sec-butylpyrroline-2-ketone, a natural substance, and their potential use in agriculture for weed control. Through the modification of the 5-sec-butyl hydrocarbon chain and 3-acetyl group and the analysis of their biological functioning, newly designed molecules are superior to the original compound in herbicidal activity. These molecules inhibit the photosynthesis of the plants. The treated plants show significant damage in 24 hours and die within 3-5 days after the chemical treatment. In addition, the new molecule has relatively simple structure, they are easy to make and they have better physical properties. They are broad-spectrum, high potency herbicides.

Acylaminoacetyl Derivatives of Active Methylene Compounds. 2. The Cyclization of the Acetylaminoacetyl Derivatives to α-Substituted Tetramic Acids and the Formation of N-Acetyl-α-substituted Tetramic Acids

The reaction of aceturic acid p-nitrophenyl ester with active methylene compounds Y-CH2-CO2R has been found to give either the normally expected C-acylation compounds 2 (Y = -CN, -CO2R, -COCH3) or N-acetyl-α-Y-substituted tetramic acids 3 (Y = -CO2R, -COC

Acylaminoacetyl Derivatives of Active Methylene Compounds. 1. The Cyclization of the Benzoylaminoacetyl Derivatives to α-Substituted Tetramic Acids (1)

Hippuric acid was converted to α-Y-substituted tetramic acids (Y = -CN, -CO2R and -COCH3) according to the following general scheme of reactions: a) preparation of the hippuric acid chloride or of its p-nitrophenyl ester; b) C-acylation of an active methy
