Tryptophol derivatives are very important compounds with wide spectrum of pharmaceutical and physiological activity. Herein, the esterification reaction of trypthol and its derivatives with β,γ-unsaturated α-keto acids was reported by the use of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI) and 1-hydroxybenzotriazole (HOBt) as conden-sation reagents. A series of β,γ-unsaturated α-keto trypanol ester derivatives were prepared in moderate to high yields. This method has advantages of riched functional group tolerance, readily available starting materials and easy operation.

Key words: condensation reagent, tryptophol, esterification, β,γ-unsaturated α-keto acid, β,γ-unsaturated α-keto trypanol ester
