structurally related to the previously described N‐4‐arylpiperazin‐1‐yl amides of 2‐aza‐1,3‐dioxospiro[4.5]dec‐2‐yl‐acetic acid, were synthesized. The designed compounds 5–15 were prepared by condensation of the formerly obtained (2‐aza‐1,3‐dioxospiro[4.5]dec‐2‐yl)‐ (3) and (2‐aza‐1,3‐dioxo[4.4]non‐2‐yl)‐(4) propionic acids with the appropriately substituted 4‐arylpiperazines, in the presence of the
