New, abridged pathway to Masamune's "southern hemisphere" intermediate for the total synthesis of bryostatin 7.

[reaction: see text] The "Southern Hemisphere" intermediate 2, used by Masamune and co-workers for their asymmetric total synthesis of bryostatin 7 (1), has been synthesized from (E)-1,4-hexadiene (11) by a 24-step pathway that has a longest linear sequen
