Reassigning the structure of Dolastatin based upon his total synthesis of Callipeltoside, Paterson used two 1,4-syn boron aldol reactions to configure a considerable section of Dolatstatin, finishing the total synthesis in a neat 23-step campaign. The sugar-unit was derived directly from L-rhamnose, appending in moderate yield, but with impressive stereochemical control.
