a structurally simplified inhibitor is introduced. The modes of 5‐LO inhibition by CYN and the synthetic inhibitors cannot be assigned to any of the known categories of lipoxygenase inhibitors. These compounds clearly interfere directly with 5‐LO and represent rather small and flexible molecules, with unique structures among 5‐LO inhibitors identified thus far.
2-Alkyl-2,4-diacyloxy-but-3-enals of the formula ##STR1## where R.sup.1 is alkyl and R.sup.2 is hydrogen, alkyl, a cycloaliphatic radical or an aromatic radical, are prepared by reacting a buta-1,3-diene of the formula ##STR2## with an oxygen donor. The new compounds are valuable intermediates in the preparation of terpenes, e.g. retinal, .beta.-carotin and apocarotinoids.
