PREPARATION:A carboxylic acid derivative shown by the formula III is condensed with an amine shown by the formula IV in an aprotic solvent such as preferably DMF, etc., in the presence of a condensation agent (e.g., diethylphosphoric acid cyanide, etc.). 展开 ...
Carboxylic acid - Hydroxy, Keto, Acids: The 2-, 3-, 4-, and 5-hydroxycarboxylic acids all lose water upon heating, although the products are not the same. The 2-hydroxy acids form cyclic dimeric esters (formed by the esterification of two molecules of th

The synthesis of the β-iodo-α,β-unsaturated carboxylic acid 176, has been achieved from the corresponding β-stannyl-α,β-unsaturated carboxylic acid. The stereoselective synthesis of the desired vinylstannane starting material was undertaken via a stannylcupration of the corresponding alkyne-appende...

The present invention relates to new substituted carboxylic acid amides of general formula wherein A, B and R1 to R5 are defined as in claim 1, the tautomers, the enantiomers, the diastereomers, the mixtures thereof and the salts thereof, particularly the physiologically acceptable salts thereof...
This invention relates to a novel carboxylic acid ester represented by the following general formula (I) and an insecticidal and/or acaricidal composition containing the same as an active ingredient:
6. The carboxylic acid derivative containing the thiazole ring of any one of claims 1, which is represented by a substituent selected from (34) 2-[(4-{2-[(4′-fluorobiphenyl-4-yl)oxy]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid (38) 2-[(4-{2-[(4′-chlorobiphenyl-4-yl...
