Highly functionalized pyrans designed for multipoint side chain attachment to the F-ring sector of spongistatin 1 (altohyrtin A)

The synthesis of three potential F-ring components, variably functionalized for attachment to the chlorodiene side chain by differing chemical means, has been accomplished from D-(+)-mannose as the generic precursor.
