The optimisation of a synthetic strategy towards the ABC segment of the cytotoxic macrolide spirastrellolide A is reported, together with its application to the synthesis of two diastereomeric C1âC22 fragments for stereochemical correlation purposes with a putative spirastrellolide degradation product.
