An effective totalsynthesis of the marine sponge cytotoxin (+)-psymberin [irciniastatin A (1)] has been achieved. Highlights of the strategy include a Diels-Alder reaction between a bis-siloxy diene and an allene to construct the aromatic ring, a boron-mediated aldol reaction to elaborate the C(15-17) all syn stereotriad, catalytic reagent control to set the C(8, 9, 11 and 13) stereogenic centers
