## Abstract The sequence‐dependent, acid‐ or base‐catalysed aspartimide formation is one of the most serious side reactions in solid‐phase synthesis of peptides containing aspartic acid. In the present work, we investigated the susceptibility of 4‐{__N__‐[1‐(4,4‐dimethyl‐2,6‐dioxocyclohexylidene)‐3
