1,1-Dialkylethenes are readily prepared in good yields from vinyltrialkylborates derivedfrom trialkylboranes and trisylhydrazones of methyl ketones by treatment with iodine.

In the preceding letter, we described a synthesis of the conserved C.1-C.13 hydrophobic domain common to the potent B-type amphidinolides. In this letter, we present syntheses of the C.14-C.26 hydrophilic domain specific to amphidinolide B1 and a model for uniting the hydrophobic and hydrophilic domains to form the (E)-1,1',3-trisubstituted diene.
