Synthetic efforts toward the C22-C36 subunit of halichondrin B utilizing local and imposed symmetry

(Chemical Equation Presented) The C22-C34 portion (2) of halichondrin B was synthesized from meso-symmetric bis-silyl protected cyclopentenediol (7) in 20 steps and 7% overall yield. This was accomplished through a two-directional synthesis/terminus diffe
