The antimitotic natural product spirastrellolide A is a complicated structure that shows impressive biological effects. Many key issues remain unresolved for this compound, for example its relative and absolute configurations and its biological mode of action. In two Communications on pages 5506 and 5510 ff., Fürstner and co-workers describe the synthesis of all four fragments of spirastrellolide A—initial strides in answering these questions.
