Abstract It is shown that the acetylation of synthetic crustaxanthin with acetic anhydride in pyridine yields the tetraacetate and not the diacetate as claimed. Even more voluminous reagents such as bis‐trimethylsilylacetamide, pivaloyl or 1‐adamantoyl chloride give rise to tetraester. The identification of these derivatives was accomplished through spectral data.
