l-Tyrosine is an efficient catalyst for the condensation of substituted indole-3-aldehydes 1(a-d), N-methyl indole-3-aldehydes 4(a-d), and N-ethyl indole-3-aldehydes 6(a-d) with meldrum's acid (2) containing a cyclic active methylene group to produce 3(a-d), 5(a-d), and 7(a-d), respectively, in water at room temperature for 30 min. The antimicrobial activities of 3(a-d), 5(a-d), and 7(a-d) have been studied.
