The unidentified configurations at C5 and C10 incallystatin A (1), a potent cytotoxic polyketide from the marine sponge Callyspongia truncata, were determined to be R,R by comparing the circular dichroism spectrum of 1 with those of two model compounds 2 and 3. Compounds 2 and 3 were synthesized by using E-selective Wittig olefination at the C6-C7 position as a key reaction.
