L-Tyrosine as an efficient catalyst for the Knoevenagel condensation of substituted indole-3-aldehydes 1(a-d), N-methyl indole-3-aldehydes 4(a-d), N-ethyl indole-3-aldehydes 6(a-d) with barbituric acid (2) containing cyclic active methylene group to produce 3(a-d), 5(a-d) and 7(a-d), respectively in water at room temperature for 10 min. The antimicrobial activities of 3(a-d), 5(a-d) and 7(a-d) have been studied.
L-酪氨酸作为一种高效催化剂,促进取代的吲哚-3-醛1(a-d)、N-甲基吲哚-3-醛4(a-d)、N-乙基吲哚-3-醛6(a-d)与含有环状活性亚甲基基团的巴比妥酸(2)在室温下水相中反应10分钟,生成3(a-d)、5(a-d)和7(a-d)。已研究了3(a-d)、5(a-d)和7(a-d)的抗菌活性。
