(Chemical Equation Presented) A short sequence based on asymmetric catalysis, chirality transfer, and an optimized carbometallation protocol gave an anti,anti stereotriad building block in six steps. Both enantiomers of the chirality source, N-methyl ephedrine, are inexpensive, and the auxiliary is recoverable. In one chiral series, the building block was converted to the B-2 intermediate in Miyashita's synthesis of scytophycin C; in the enantiomeric series, it was converted to a key intermediate for aplyronine A and to the polyketide cap for the callipeltins.
