Popis: The transformation of the acyclic precursor previously employed in the synthesis of talaromycin B to the stereoisomeric avian toxin talaromycin A is described. Diastereotopic selectivity at prochiral carbon centers in an acetonide migration and in a subsequent spiroketalization reaction provides the stereocontrol required for the synthesis.
