Abstract:

We report the first trifluoroacetic anhydride-and trifluoroacetic acid-promoted cascade reaction with phloroglucinoltribenzyl ether and carboxylic acid as starting materials. By simply varying the temperature of systems containing the same starting materials, different products were produced in high yields. A three-step consecutive reaction process was also proposed.

Key words: Cascade reaction, Phloroglucinol, Trifluoroacetic anhydride(TFAA), Trifluoroacetic acid(TFA)
