Starting with (S)-O-benzylglycidol (9) as only chiral building block, a formal synthesis of protomycinolide IV (1) and the first syntheses of its presumed biogenetic precursors methyl epimycinonate I (2), methyl mycinonate I (3), methyl mycinonate II (4), and decarboxymycinonic acid III (5), have been achieved via the eight-carbon unit (8) as a common intermediate.
