A stereocontrolled synthesis of the C1-C21 [6,6]-spiroacetal-containing domain of the originally assigned structure of spirastrellolide A is reported, exploiting asymmetric boron aldol methodology and an alkyne addition to a C17 aldehyde. Comparison of the 1H NMR data obtained for this synthetic fragment with that for the corresponding region of spirastrellolide suggested some stereochemical reassignment was required.
