Novel targeting herbicide have no side effect on non-target organisms as well as reduce environmental pollutants [3]. Nevertheless, several target enzymes involved in amino acid biosynthesis were validated as promising leads for a novel mode of action herbicidal compound. For example, dihydroxy acid ...
S. Therefore, the structure was determined to be 3S-5, 8-dihydroxy-3-hydroxymethyldihydroisocoumarin and was named as botryoisocoumarin A. In addition, five known compounds (2–6) were isolated and identified as monocerin (2),27 3-methyl-6,8-dihydroxyisocoumarin (3),28 8-methoxymellein ...
2.1.3. General procedure for the synthesis of Benzylidene-(5-p-tolyl-[1,3,4]thiadiazol-2-yl)-amine 3 A mixture of 2 (0.01 mol) and benzaldehyde (0.01 mol) was refluxed in ethanol for 5 h with a few drops of glacial acetic acid. The solid separated on cooling was filtered, dried ...
Imines 24 were generated in situ by homocondensation of benzylamines 23 using 4,6-dihydroxysalicyclic acid as an organocatalyst and molecular oxygen as a co-oxidant. Imines 24 were then treated with acyl chlorides and triethylamine in the presence of molecular sieves in acetonitrile at 0°-rt...
The highest enantioselectivity was attained with the aromatic benzaldehyde (entry 4, ee = 96%), but the yield is significantly lower than for aliphatic aldehydes. This is mainly a consequence of the marked sensitivity towards elimination of 4-aryl substituted 2-oxetanones explaining a partial ...
