Applications of 3-phenylbut-2-enoic acid_Kain Industrial Additives

Overview[1][2] 3-Phenylbut-2-enoic acid can be prepared in one step from triethyl phosphonoacetate and phenylacetaldehyde, and can be used to synthesize 2-position disubstituted indolin-3-one compounds. Substituted indolin-3-one structures are widely found in biologically active natural product molecules. Preparation[1] In a 100 mL two-neck round-bottom flask equipped with a magnetic stir bar, thermometer and condenser, add triethyl…
