- Activation of hydrocinnamic acids with pentafluorophenol versus pentafluorothiophenol: Reactivity towards hexylamine
-
In this work we describe and compare the synthesis of four new hexylamides of hydrocinnamic acids, namely hexylamide of hydrocinnamic, 3,4-dimethoxyhydrocinnamic, 4-hydroxy-3-methoxyhydrocinnamic and 3,4-dihydroxyhydrocinnamic acids via pentafluorophenyl

- Efficient synthesis of thioesters and amides from aldehydes by using an intermolecular radical reaction in water
-
The combination of the water-soluble radical initiator, 2,2′-azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride (VA-044) and the surfactant, cetyltrimethyl-ammonium bromide (CTAB), was found to be the most suitable condition for the effective and direct synthesis of useful active thioesters (pentafluorophenyl thioesters) in water. In addition, the direct amidation of aldehydes was achieved by the addition of the amines to the thioesterification reaction mixture in water.
