by us established the catechol motif as being essential for good anti-Aβ aggregation activity. Here, we described the syntheses of derivatives of clovamide (5) and caffeoyl-N-tyrosine (6), natural products based on the amino acids L-dopa and L-Tyr, respectively, which incorporate the catechol motif. The syntheses of series of L-dopa (21–25) and L-Tyr (26–29) derivatives, as well as 11-13 are also reported
